Description
Bekledd elektrode for elektrisk lysbuesveising. Coated electrode for electric arc welding.
Nærværende oppfinnelse vedrører en The present invention relates to a
elektrode for elektrisk lysbuesveising med kjerne av jern eller stål og med et slaggdannende hylster, hvis ytre diameter utgjør mellom 1,5 og 2 ganger kjernediameteren og hvis slaggdannende bestanddeler i det vesentlige består av kalsiumkarbonat (eventuelt sammen med barium- og/eller magnesiumkarbonat og flusspat samt eventuelt kryolitt. Elektroder av denne såkalte basiske type gir som bekjent et sveisegods av særdeles god kvalitet og har derfor fått stor anvendelse. Dette gjelder særlig den nyere type av disse elektroder som er gjort mer lettsveiset ved tilsetning av en viss mengde jernpulver i hylsteret, f. eks. tilsvarende et utbytte av ca. 112—115 pst. electrode for electric arc welding with a core of iron or steel and with a slag-forming sheath, the outer diameter of which is between 1.5 and 2 times the core diameter and whose slag-forming constituents essentially consist of calcium carbonate (possibly together with barium and/or magnesium carbonate and fluorspar as well as possibly cryolite. As is well known, electrodes of this so-called basic type provide weld material of particularly good quality and have therefore been widely used. This particularly applies to the newer type of these electrodes, which are made easier to weld by adding a certain amount of iron powder in the casing, eg equivalent to a dividend of approx. 112-115 per cent.
De basiske elektroders sveiseegenskaper The welding properties of the basic electrodes
lar imidlertid ennå noe tilbake å ønske. Ved sveising i andre sveisestillinger enn den ho-risontale, spesielt ved vertikalsveising har de en viss tilbøyelighet til å kortslutte mot og festne til arbeidsstykket og fordrer derfor en dyktig sveiser. Videre egner de seg vanligvis mindre godt for vekselstrømsveis-ing, idet buen er tilbøyelig til å slukne. Un-der visse forhold kan en tendens til pore-dannelse vise seg. however, still leaves something to be desired. When welding in welding positions other than horizontal, especially when welding vertically, they have a certain tendency to short out and stick to the workpiece and therefore require a skilled welder. Furthermore, they are usually less suitable for alternating current welding, as the arc is prone to extinguishing. Under certain conditions, a tendency to pore formation may appear.
Oppfinnelsen har til hensikt å forbedre de basiske elektroder og består i det vesentlige deri at hylsteret inneholder såvel strontiumkarbonat som zirkonoksyd, fortrinsvis i form av zirkonsand (mineralsk zirkonsilikat) i en mengde som for hvert av stoffene ligger mellom 2 og 15 pst. av den totale vekt av hylsterets ikke-metalliske bestanddeler. Til den angitte mengde zirkonoksyd svarer en zirkonsandmengde på omkring 3—20 pst. The invention aims to improve the basic electrodes and essentially consists in the case containing both strontium carbonate and zirconium oxide, preferably in the form of zircon sand (mineral zirconium silicate) in an amount which for each of the substances is between 2 and 15 percent of the total weight of the casing's non-metallic components. The specified amount of zircon oxide corresponds to an amount of zircon sand of around 3-20 per cent.
Ved oppfinnelsen oppnåes en vesentlig forbedring av sveiseegenskapene, uten at den for de basiske elektroder utmerkede gode sveisekvalitet forringes. Tvertimot ty-der de nå foreliggende resultater på en viss bedring av sveisegodsets slagseighet. Elek-trodene lar seg uten vanskelighet sveise med vekselstrøm og stiller ved vertikalsveising mindre krav til sveisernes dyktighet enn de kjente basiske elektroder. With the invention, a significant improvement of the welding properties is achieved, without the excellent welding quality of the basic electrodes being impaired. On the contrary, the current results indicate a certain improvement in the impact strength of the weld metal. The electrodes can be welded with alternating current without difficulty and, in the case of vertical welding, make fewer demands on the welder's skill than the known basic electrodes.
Den forbedring som oppnåes ved oppfinnelsen synes å stå i forbindelse med en viss konstatert minskning av størrelsen av de dråper som passerer over ved sveisingen. Elektrodehylsteret ifølge oppfinnelsen har videre en økende tendens til kraterdannel-se, hvilket tilskrives zirkonoksyd- resp. zir-konsandtilsetningen. The improvement achieved by the invention seems to be in connection with a certain ascertained reduction in the size of the drops that pass over during the welding. The electrode sleeve according to the invention also has an increasing tendency to crater formation, which is attributed to zirconium oxide or the zir consonant addition.
Foruten de ovenfor omtalte bestanddeler kan hylsteret inneholde andre i basiske elektroder kjente eller passende tilset-ninger, som f. eks. ferromangan, ferrokisel og andre ferrolegeringer, mangandioksyd In addition to the components mentioned above, the casing can contain other known or suitable additives in basic electrodes, such as, for example, ferromanganese, ferrosilicon and other ferroalloys, manganese dioxide
eller manganmalm og titandioksyd. Hvis titandioksyd inngår, bør innholdet av dette or manganese ore and titanium dioxide. If titanium dioxide is included, the content of this should
ikke overstiger 5 pst. av vekten av hylsterets does not exceed 5 percent of the weight of the casing
ikke-metalliske del, og helst ikke overstige 3 a 3,5 pst. av nevnte vekt. non-metallic part, and preferably not exceeding 3 to 3.5 per cent of said weight.
Som eksempel på slagdannende kom-posisjon ifølge oppfinnelsen kan angis føl-gende: As an example of an impact-forming composition according to the invention, the following can be stated:
Vektforholdet mellom kalksten og flusspat kan variere mellom ca. 2 : 1 og 1 : 1 og The weight ratio between limestone and fluorspar can vary between approx. 2 : 1 and 1 : 1 and
velges fortrinsvis nærmere den førstnevnte is preferably chosen closer to the former
verdi. Til den angitte slaggdannende kom-posisjon settes 35 vektdeler jernpulver eller value. 35 parts by weight of iron powder or
en blanding av jernpulver med ferrokisel a mixture of iron powder with ferrosilicon
og/eller ferromangan, samt som bindemid-del vannglass, fortrinsvis kalivannglass, i and/or ferromanganese, and as a binder water glass, preferably potash water glass, i
den mengde som er nødvendig for å gjøre the quantity necessary to make
massen pressbar. Massen anbringes på the mass compressible. The mass is placed on
kjernetråder av bløtt stål med 3,25 mm diameter ved hjelp av strengpresning gjennom mild steel core wires of 3.25 mm diameter by means of strand pressing through
et munnstykke med 5,9 mm diameter. a nozzle with a diameter of 5.9 mm.
