Description

  The present invention relates to a welding wire storage container and a container-containing welding wire for storing a coil of a welding wire, and more particularly to a welding wire storage container and a container-containing welding wire that can be applied to a welding wire having high rigidity such as a solid wire.

  As a container for storing a welding wire such as a solid wire and a flux-cored wire, a bottomed cylindrical pail container is generally used (for example, see Patent Documents 1 and 2). FIG. 5A is a perspective view schematically showing a conventional welding wire in a container, and FIG. 5B is a cross-sectional view thereof. FIG. 6 is a perspective view showing a pressing plate of a conventional welding wire storage container. As shown in FIGS. 5 (a) and 5 (b), the conventional welding wire with a container is configured by holding the bottom plate 105 by caulking the lower part of the outer cylinder 101, and the container is configured in this container. A welding wire 100a is dropped and stored while moving and displacing the central axis along a circular locus. In the conventional welding wire storage container, the inner cylinder 106 having a smaller diameter than the outer cylinder 101 may be provided coaxially with the outer cylinder 101.

  Usually, the welding wire with a container is unwound in a state of being accommodated in the container. For this reason, the welding wire 100a may be entangled or entangled during unwinding. Therefore, in some conventional welding wires with a container, an annular pressing plate 112 shown in FIG. 6 is placed on the welding wire coil 100. The presser plate 112 has a plurality of blade bodies 112a having an L-shaped cross section that protrudes to the outside of the outer peripheral portion of the presser plate 112 so that the welding wire 100a does not jump out of the gap between the outer cylinder 101 and the presser plate 112. It is provided at equal intervals. The blade body 112a is made of a foamed urethane sponge and bonded to the surface of the pressing plate 112 with an adhesive. Since the holding plate 112 can move in the vertical direction, when the welding wire 100a is unwound and the height of the welding wire coil 100 is lowered, the holding plate 112 is also lowered. It is always placed on the welding wire coil 100. Further, a window 112b made of a hole having a diameter of 30 to 60 mm is provided at a position between the blade bodies 112a of the holding plate 112 so that the remaining amount of the welding wire in use can be visually confirmed.

  On the other hand, in order to prevent entanglement during unwinding, a pressing plate in which a plurality of elastic inward pieces are provided on a strip-like vertical wall portion has also been proposed (see Patent Document 3). The pressing plate is rounded into an annular shape, and is placed on the welding wire coil such that the vertical wall portion is in contact with the inner surface of the outer cylinder and the elastic inward piece is in contact with the upper surface of the welding wire. Then, the welding wire is drawn upward while being in contact with the edge of the elastic inward piece of the pressing plate.

  However, in the conventional welding wire storage container, the bottom plate 105 is fixed by caulking the lower end portion of the outer cylinder 101 as shown in FIG. A small caulking portion is formed. This caulking portion is intended to facilitate positioning when the bottom plate 105 is inserted into the outer cylinder 101 and to assist by applying a guide during curl processing for fixing the bottom plate 105. When unraveling, the presser plate 102 is held by the caulking part, and the welding wire coil 100 below the caulking part cannot be pressed, and the wire between the caulking part and the bottom plate 105 jumps up, becomes entangled and loosened. There is a problem of injury.

  Thus, a method of raising the bottom of the container by laminating a plate or the like on the bottom plate 105 has been studied. FIG. 7 is a cross-sectional view showing a welding wire storage container with a raised bottom. In this welding wire storage container, a disk 109 having an outer diameter that can be inserted into the caulking portion and having a thickness equivalent to the height of the caulking portion is joined to the bottom plate 105 with an adhesive or the like. As a result, the bottom of the container is raised and the upper surface of the lowermost welding wire is above the caulking portion, so that the lowermost welding wire can be pressed by the pressing plate 102. In the welding wire storage container shown in FIG. 7, a ring-shaped restraining tool 103 is placed on the presser plate 102, and the length of the outer tube is between the outer tube 101 and the outer edge of the presser plate 102. A string 108 extending in the direction is provided. The string 108 passes through the inside of the restraining tool 103.

  In addition, a holding plate is provided which has a plurality of strip-shaped blade members attached to an annular flat plate whose inner diameter is larger than the outer diameter of the inner cylinder and whose outer diameter is smaller than the minimum inner diameter of the outer cylinder so as to protrude inward and outward. A welding wire storage container has also been studied (see Patent Document 5). FIG. 8 is a plan view showing a pressing plate of the welding wire storage container. The holding plate 120 presses the welding wire coil downward by the annular flat plate 121 and prevents the welding wire on the outer cylinder side and the inner cylinder side from jumping out by the blade member 122. Since this presser plate 120 can enter the caulking portion whose outer diameter is smaller than the inner diameter of the caulking portion, it is possible to press down to the lowermost welding wire.

Japanese Examined Patent Publication No.59-8474 (Page 1-2, Figure 1-4) Japanese Examined Patent Publication No. 3-34424 (Fig. 2-3, Fig. 1) JP-A-10-218493 (Figs. 3-4 and 1-3) Japanese Patent Publication No. 1-15353 (page 2-3, Fig. 3) Japanese Patent Laid-Open No. 2-147666 (page 3-5, FIG. 2)

  However, the conventional techniques described above have the following problems. First, the conventional pressing jig shown in FIG. 6B includes a pressing plate 112 made of a ring-shaped molding plate made of a single material of olefin resin such as ABS, PP, PS, and a plurality of urethane sponges. Since it is composed of the blade body 112a, there are the following problems. That is, when the blade body 112a made of foamed urethane sponge is weakened in contact with the inner surface of the outer casing 101 of the pail container due to a change with time, and the welding wire just before being pulled over the blade body 112a, the welding wire becomes a blade body. As a result, the wire is not easily returned to the original state, that is, below the presser plate 112, and the wire feeding is stopped. In addition, a break is likely to occur from the vicinity of the joint between the presser plate 112 and the blade body 112a, and when the welding wire enters the break, a situation where the wire feeding is stopped similarly occurs.

  In addition, the conventional welding wire storage container with the raised bottom shown in FIG. 7 can be pressed down to the lowest layer of the welding wire coil 10 by the pressing plate 102, but the disk 109 and the inner surface of the outer cylinder 101 There is a problem that a gap is formed between the wires, and a wire is caught in the gap to stop feeding. When using a plurality of container welding wires in succession, it is impossible to move to the next container unless all the welding wires stored in the container are pulled out smoothly. If trouble occurs in the vicinity of the bottom where the remaining amount of metal is reduced, it is not possible to continuously use a plurality of container-containing welding wires. Further, it is possible to eliminate the gap between the disk 109 and the inner surface of the outer cylinder 1 by increasing the thickness of the disk 109 and setting the bottom of the container above the caulking portion. An increase in the amount is not preferable because the amount of wires that can be accommodated in the container decreases, the workability during use decreases, and the manufacturing cost increases.

  Furthermore, since the conventional welding wire storage container provided with the holding plate 120 shown in FIG. 8 has only a few portions between the holding plate 120 of the welding wire coil and the outer cylinder being pressed by the blade material 122, There is a possibility that the welding wire on the outer cylinder side jumps out. In addition, since the blade member 122 protruding inward contacts the outer surface of the inner cylinder and the blade member 122 protruding outward moves in a downward direction while contacting the inner surface of the outer cylinder, the pressing plate 120 is inclined easily. There is a problem that entanglement and entanglement of the wire are likely to occur.

  The present invention has been made in view of such problems, and provides a welding wire storage container and a container-containing welding wire that can smoothly unwind the welding wire to the lowest layer without causing entanglement and entanglement. With the goal.

  A welding wire storage container according to the present invention is a welding wire storage container for storing a coil of a welding wire, and is held inside the outer cylinder by caulking the outer cylinder forming a container side wall and the outer cylinder. A bottom plate forming a container bottom, a pressing jig placed on a welding wire coil housed on the bottom plate, and extending between the outer cylinder and the pressing jig in the height direction of the outer cylinder. A plurality of strings fixed to the upper and lower ends of the outer cylinder, and an annular string restraint disposed on the pressing jig and passing through the string. The jig has a shape in which a ring-shaped flat plate portion on the stored welding wire and a weir portion rising upward from the outer edge of the entire flat plate portion are integrally formed, and the flat plate portion and the weir The lower part of the part is the inside of the caulking part of the outer cylinder Smaller, upper portion of the dam portion may be greater than the inner diameter of the caulked portion.

  In the present invention, the holding jig placed on the welding wire coil has a weir portion rising outward from the flat plate portion, and a plurality of strings extending in the height direction of the outer cylinder on the inner surface of the outer cylinder Since this string is provided so as to pass through the inside of an annular string restraint disposed on the holding jig, when unwinding the coil of the welding wire, the wire is It is possible to prevent the coil winding state from being disturbed by protruding from between the inner surface of the outer cylinder and the inner surface of the outer cylinder. In addition, since the holding jig has a lower portion of the flat plate portion and the weir portion smaller than the inner diameter of the caulking portion of the outer cylinder, the lower portion of the flat plate portion and the weir portion can be fitted into the caulking portion. . Therefore, even if the remaining amount of the welding wire coil decreases, the holding jig can reliably hold the upper surface of the welding wire coil. Thereby, even if it does not raise a bottom etc. like the conventional welding wire storage container, it can unwind smoothly, without producing a tangle and a tangle up to the welding wire of the lowest layer.

  In the welding wire container according to the present invention, the dam portion is inclined so that the upper portion extends outward from the lower portion, and the angle further horizontally from the first portion further outward or smaller than the first portion. It is preferable to have the 2nd part which spreads by.

  Moreover, in this invention, it can also comprise so that it may have an inner cylinder arrange | positioned coaxially with the said outer cylinder.

  The pressing jig is integrally formed of an olefin resin such as ABS (Acrylonitrile-Butadiene-Styrene) resin, PP (Polypropylene) resin, or PS (Poly-Styrene) resin. It is preferable that

  Further, the pressing jig has a plate thickness of 1.5 to 6 mm, the flat portion outer diameter is 5 to 30 mm smaller than the inner diameter of the caulking portion, and the flat portion inner diameter is smaller than the outer diameter of the inner cylinder. Preferably, the outer diameter of the upper portion of the weir portion is 20 to 40 mm larger, the outer diameter of the upper portion is 8 to 20 mm smaller than the inner diameter of the outer cylinder, and the height of the weir portion is 15 to 30 mm.

  In the flat plate portion of the pressing jig, one or a plurality of holes for visually recognizing the lower welding wire are provided at equal positions around the center of the pressing jig. Is preferably 2 to 20 mm and a length of 10 to 50 mm.

  The welding wire with a container according to the present invention is characterized in that a coil of a welding wire is accommodated in the welding wire storage container. The welding wire with a container has a locking portion that is provided on an upper portion of the outer cylinder and locks the unwinding end portion of the welding wire coil. The welding wire unwinding start end portion of the welding wire coil stored in the welding wire storage container is connected to each other, and a plurality of welding wire coils can be continuously unwound.

  According to the present invention, when the welding wire is unwound from the welding wire coil, the welding wire is prevented from being violated by the pressing jig, and the welding wire is provided by the string restrained so as to pass inside the string restraining tool. Is prevented from popping upward from the gap between the holding jig and the outer cylinder. The holding jig has a flat plate portion and a lower portion of the weir portion that are smaller than the inner diameter of the caulking portion of the outer cylinder. Therefore, when the remaining amount of the welding wire coil decreases, The one-side portion can be fitted into the caulking portion to reliably press the upper surface of the welding wire coil. Thereby, even if it does not raise a bottom etc. like the conventional welding wire storage container, it can unwind smoothly, without producing a tangle and a tangle up to the welding wire of the lowest layer.

  Further, as in claim 4, by forming the pressing jig in which the weir portion and the flat plate portion are integrally formed by integrally molding with an olefin resin, a blade body made of urethane foam sponge as in the prior art. The deterioration of the pressing force on the inner surface of the outer cylinder due to the change with time can be further prevented as compared with the case where is provided.

  Hereinafter, a welding wire container according to an embodiment of the present invention will be specifically described with reference to the accompanying drawings. 1 is a cross-sectional view showing a welding wire storage container of the present embodiment, FIG. 2 is a cross-sectional view of a holding jig, FIG. 3 is a perspective view showing the entire welding wire storage container, and FIG. 4 is a perspective view of the pressing jig. is there. In the welding wire storage container of the present embodiment, the lower end portion of the cylindrical outer cylinder 1 is caulked, and the disc-shaped bottom plate 5 is fixed, whereby the bottom plate 5 is held at the lower end portion of the outer cylinder 1. A sealed container is constructed. Therefore, the inner diameter of the inner surface of the outer cylinder 1 is small in the caulking portion 1a at the lower end. The bottom plate 5 and the outer cylinder 1 can also be fixed in a mutually reinforcing manner by a metal reinforcing band (not shown) that wraps the caulking portion 1 a of the outer cylinder 1 and the bottom surface of the bottom plate 5. Generally, since a welding wire of 200 to 500 kg is stored in a welding wire storage container, a safe and robust structure is required during transportation and hanging transfer. For this reason, from the viewpoint of weight reduction and electrical insulation, the outer cylinder 1 in the welding wire storage container of the present embodiment is formed of thick paper or the like.

  In the welding wire storage container of the present embodiment, a cylindrical inner cylinder 6 having a diameter smaller than that of the outer cylinder 1 is disposed coaxially with the outer cylinder 1 inside the outer cylinder 1. The part is fixed on the bottom plate 5. A welding wire coil 10 is placed on the bottom plate 5 between the outer cylinder 1 and the inner cylinder 6. The welding wire coil 10 is formed by filling the welding wire 10a with a twist of about 360 ° per turn in a loop shape in the space between the inner cylinder 6 and the outer cylinder 1 and dropping it. Stored.

  In the welding wire storage container of the present embodiment, the holding jig 2 is placed on the welding wire coil 10. As shown in FIGS. 2 and 4, the holding jig 2 is composed of a ring-shaped flat plate portion 3 and a cylindrical weir portion 4 that rises upward from the entire circumference of the outer edge of the flat plate portion 3. When the welding wire coil 10 is accommodated, the flat plate portion 3 is placed thereon.

  The weir portion 4 has a lower portion (and hence the flat plate portion 3) smaller than the inner diameter of the caulking portion 1a of the outer cylinder 1, and an upper portion larger than the inner diameter of the caulking portion 1a. Thereby, the upper end part of the dam part 4 has a magnitude | size which can raise / lower along the inner surface of this outer cylinder 1 in the vicinity of the inner surface of the outer cylinder 1, and the lower part of the flat plate part 3 and the dam part 4 is in the caulking part 1a. It has a size that can be fitted in.

  Specifically, the weir portion 4 has a first portion 4a that is inclined so that the upper portion extends outward from the lower portion, and a first portion 4a that extends further outward from the first portion 4a or at a smaller angle than the first portion. 2 part 4b. In the example shown in FIG. 2, the second portion 4b extends horizontally outward. The second part 4b is not horizontal, and the cross section may be inclined in the same manner as the first part 4a, but the inclination angle is smaller than that of the first part 4a.

  Since the lower portion of the dam portion 4 is smaller than the inner diameter of the caulking portion 1a of the outer cylinder 1, the dam portion 4 is not limited to the example shown in FIG. It may stand vertically.

  In the flat plate portion 3, for example, two slit-shaped holes 8 are formed at equal intervals with the longitudinal direction thereof directed in the radial direction of the ring-shaped flat plate portion 3. The hole 8 has, for example, a slit shape or a rectangular shape with a width of 2 to 20 mm and a length of 10 to 50 mm. The remaining amount of the welding wire coil 10 below the pressing jig 2 is formed by the hole 8. Can be visually recognized. In FIG. 4, the hole 8 has a slit shape or a rectangular shape, but the shape of the hole 8 is not limited to this. In the embodiment shown in FIG. 4, two holes 8 are formed. However, the present invention is not limited to this, and one or a plurality of holes 8 can be provided. Although the number of the holes 8 can be five or more, the lower welding wire can be sufficiently confirmed even if the number of the holes 8 is four or less, and the strength of the flat plate portion 3 of the holding jig 2 increases as the number of the holes 8 increases. And the lower welding wire coil 10 easily rusts through the hole 8. In any case, it is preferable to arrange the holes 8 at equal intervals.

  Next, a preferable material and a preferable shape and size of the holding jig 2 of the welding wire storage container configured as described above will be described. The holding jig 2 is formed by integrally forming a flat plate portion 3 and a weir portion 4 with an olefin resin or the like. As this olefin resin, there are ABS (Acrylonitrile-Butadiene-Styrene) resin, PP (Polypropylene) resin, PS (Poly-Styrene) resin, etc., which are injection-molded and the like. The holding jig 2 can be obtained by molding according to the above.

  The holding jig 2 has a thin wall thickness (a) (see FIG. 2) of 1.5 to 6 mm. The plate thickness of the holding jig 2 is preferably 1.5 mm or more in order to secure a necessary weight by the resin molded body, and preferably 6 mm or less so as not to be difficult to place in the outer cylinder container. . The outer diameter (d) of the holding jig 2 is preferably 8 to 20 mm smaller than the inner diameter of the outer cylinder 1 in consideration of prevention of wire jumping and smooth lowering. The inner diameter (b) of the holding jig 2 (the flat plate portion 3) is such that the wire can be pulled out smoothly without bending, and the outer cylinder 6 has an outer surface to prevent the wire from jumping up. It is preferably 20 to 40 mm larger than the diameter. Further, the outer diameter (c) of the flat plate portion 3 is 5 to 30 mm smaller than the inner diameter of the caulking portion 1 a of the outer cylinder 1 (the minimum inner diameter of the outer cylinder 1), and the first rising from the outer edge of the flat plate portion 3. It is preferable that the lower part of the part 4 a has a size that fits inside the caulking part 1 a of the outer cylinder 1. The height (e) of the weir part 4 is preferably 15 to 30 mm.

  In the present embodiment, a plurality of strings 7 are arranged so as to extend in the height direction (longitudinal direction) of the outer cylinder 1, and are fixed to the inner surface of the outer cylinder 1 at the upper part and the lower part of the outer cylinder 1 by the string fixing tool 7 a. Has been. Further, on the second portion 4 b of the dam portion 4, a ring-shaped string restraining tool 9 having a slightly smaller diameter than the inner diameter of the outer cylinder 1 is placed. And the string 7 is arrange | positioned along the inner surface of the outer cylinder 1 so that it may pass between the holding jig 2 and the inner surface of the outer cylinder 1, and may pass the inner side of the string restraint tool 9. FIG. The number of the strings 7 is three in the present embodiment, and the strings 7 are arranged at equal positions in the circumferential direction of the outer cylinder. In FIG. 1 and FIG. 3, two strings 7 are displayed for convenience. The number of the strings is not limited to three, and two or four or more may be provided.

  In addition, the said material and shape dimension are examples, and this invention is not limited to this. Further, a resin film such as a laminate film may be attached to the lower surface of the holding jig 2. As a result, the welding wire can be unwound even more smoothly, and the moisture adsorbed on the cardboard or the like can be made difficult to be transmitted to the welding wire, so that rusting can be prevented. Moreover, since the slipperiness of the wire in the contact surface of the welding wire coil 10 and the pressing jig 2 becomes good, it is possible to further prevent the wire from being tangled.

  Next, the operation of the welding wire storage container configured as described above will be described. A welding wire 10 a such as a solid wire or a flux-cored wire is dropped onto the bottom plate 5 between the outer cylinder 1 and the inner cylinder 6 to accommodate the welding wire coil 10. The welding wire coil 10 has a mass of 200 to 500 kg, for example. Then, as shown in FIG. 1, the holding jig 2 is placed on the coil 10, and the welding wire 10 a is drawn upward from the gap between the holding jig 2 and the inner cylinder 6. The terminal wire 10b serving as a wire drawing terminal is a portion that becomes a starting end when dropped into the storage container. The drawing terminal wire 10b at the starting end of the dropping is lifted up on the outer periphery of the welding wire coil 10. , Extending between the lower surface of the holding jig 2 and the upper surface of the welding wire coil 10 from the inner periphery of the holding jig 2 toward the inner surface of the outer cylinder 1. At the upper part of the inner surface, it is fixed to the inner surface of the outer cylinder by a fixing jig 11 for the lead end wire 10b. Thus, in order to fix the drawer terminating wire 10b to the upper part of the inner surface of the outer cylinder, when starting to drop the wire into the storage container, the wire dropping start end is pulled upward along the inner surface of the outer cylinder, and then the wire is stored. A coil is formed by dropping into the container, and the wire dropping start end portion is drawn across the coil to the inner peripheral side of the coil, and the pressing jig 2 is placed thereon. The string 7 is also drawn upward along the inner surface of the outer cylinder 1 and the holding jig 2 is placed on the coil 10, and then a string restraining tool 9 is placed on the holding jig 2. What is necessary is just to make it fix to the string fixing tool 7a of the inner surface upper part of the outer cylinder 1 through the inner side of the string restraining tool 9.

  In this way, after the welding wire coil 10 is stored, it is transported and stored. Then, at the welding site, the drawing start end portion (drop end portion) of the welding wire 10a is pulled out, and the drawn welding wire 10a is fed to a torch (not shown). Thereby, the welding wire in a container is used, the height of the coil 10 falls gradually, and the press jig | tool 2 on the coil 10 falls also in connection with it. At this time, since the pressing jig 2 is placed on the coil 10, it is possible to prevent the ramping when the rigid welding wire 10 a is pulled out. Further, since the string 7 restrained by the string restraining tool 9 restrains the outer periphery of the welding wire coil 10 against the outer peripheral edge of the pressing jig 2, the welding wire 10 a is connected to the inner surface of the pressing jig 2 and the outer cylinder 1. Jumping upward from the gap between the two is prevented. Thereby, the welding wire 10a is also prevented from jumping up.

  And since all or part of the 1st part 4a of the dam part 2 which stands | starts up outward from the flat plate part 3 fits in the crimping part 1a, the holding jig 2 is when the residual amount of the welding wire 10a decreases. In addition, since the flat plate portion 3 and the first portion 4a are fitted into the caulking portion 1a and the upper surface of the coil 10 is pressed, the coil 10 in the container can be pressed so as not to be exposed until the end of the drawing. That is, even when the remaining amount of the welding wire is reduced and the height of the welding wire coil 10 is lower than the caulking portion 1a of the outer cylinder 1, the lower portion 4a of the pressing jig 2 is surrounded by the caulking portion 1a. Since it enters, the pressing jig 2 can still press the upper surface of the welding wire coil 10 in the caulking portion 1a. For this reason, even if the remaining amount of the wire in the container is reduced, the holding jig 2 can reliably hold the welding wire coil 10 and smoothly wrap around the lowermost welding wire without causing entanglement and entanglement. Can be solved.

  When the drawing of the welding wire is nearing the end, the remaining amount of the coil is confirmed through the hole 8, and when the coil height is reduced to the predetermined remaining amount, the next coil storage container is moved closer. The drawing end wire 10b of the coil container being drawn out is removed from the fixing jig 11, and the drawing end wire 10b is connected to the drawing start end portion of the next welding wire by welding. To do. Thereby, welding can be performed without ending the welding process, that is, without a seam.

  Further, since the holding jig 2 is one in which the weir portion 4 and the flat plate portion 3 are integrally formed of an olefin-based resin, as compared with the case where a blade body made of foamed urethane sponge is provided, Changes in characteristics such as material or rigidity are less likely to occur with time, and further deterioration of the pressing force on the inner surface of the outer cylinder can be prevented.

  Depending on the usage status of the welding wire, the welding may be interrupted and repair of the welding object may occur. For this reason, in order to confirm the welding wire remaining amount of a storage container so that the welding of a good separation can be performed, the window for visually checking the welding wire remaining amount is provided in the holding jig. In the case of the conventional holding jig, this visual recognition window was extremely large, so if the welding wire storage container is subject to changes in the outside air temperature and is likely to cause condensation, the holding jig The welding wire exposed through the viewing window may rust. However, in the present invention, since the visual window is a hole 8 having a width of 2 to 20 mm, the lower welding wire is not easily affected by condensation, and therefore, discoloration and rusting of the welding wire are suppressed. can do.

  Further, since the blade body 112a (FIG. 6) of the conventional pressing plate is made of foamed urethane sponge, the welding wire that directly contacts the blade body 112a is likely to be discolored or rusted. In addition, since the urethane foam sponge constituting the blade body 112a contains chlorine, if it is attempted to incinerate when the pressing plate is discarded, it becomes a source of dioxins and is difficult to discard.

  However, in the present invention, since the weir portion 4 is integrally formed of the same olefin resin material as that of the flat plate portion 3, discoloration and rust do not occur even when contacting the welding wire. In addition, since the holding jig 2 is formed of an olefin resin, scrap processing is easy, and even if the holding jig 2 is incinerated, no dioxin is generated and can be easily disposed of. .

  Further, when transporting and storing the container-containing welding wire wound and stored by the above-described method, a lid (not shown) is put on the upper end portion of the outer cylinder 1. In that case, it is preferable to arrange a spacer (not shown) made of paper or the like between the pressing jig 2 and the lid. Thereby, it is possible to prevent the welding wire coil from being unwound due to vibration during transportation and causing entanglement and entanglement.

  Furthermore, in the welding wire storage container of the present embodiment, since most of the upper surface of the welding wire coil 10 is covered by the holding jig 2, moisture does not easily enter the welding wire coil 10, and the welding wire is prevented from being rusted. The effect is excellent.
