[Industrial Field of Application] The present invention relates to a welding rod for overlaying press molds and the like. [Prior art and problems to be solved by the invention] Various types of welding rods are known that have the three elements Cu-Al-Fe as their main components, but the welding rods currently in use include the following: There are problems such as: (1) Variations in hardness occur in the welded metal parts. (2) Meltability is poor and therefore workability is not very good. (3) High cost. [Structure of the invention] The present invention comprises Al9.6-10% by weight (hereinafter simply referred to as %), Mn9.6-10%, Fe2.0-3.5%, Ni1.0-10% by weight.
When using a copper alloy welding rod with a composition of 3.0% Cu and 70% or more and applying surface hardening to a press mold, etc., it will not cause seizure or galling.
The present invention provides a welding rod for obtaining a deposited metal layer with high tensile strength and hardness. The present inventors have been conducting studies to solve the problems in the prior art described above, and have arrived at the present invention based on the results of numerous experiments. Special Publication No. 58-16749 contains Al6~12%, Si3%
Below, Mn2% or less, Ni2% or less, Fe5% or less balance
A welding rod made of Cu is disclosed, and the welding rod is coated with a coating layer to which an alloy component is added, and a high-hardness overlay alloy layer is provided by a melting reaction with the coating layer. The present invention has a higher Mn component ratio and a higher Al and Mn component ratio than those described in the publication, so that welding is possible without providing a coating layer, and the hardness of the overlay alloy described in the publication is
Compared to HB240 to 280, a build-up alloy with high hardness of HB290 or higher can be obtained. The welding rod of the present invention is currently commonly used.
It can be used with TIG or MIG welding machines, and if a lime-based coating (borax, boric acid) is used as the coating (flux), it can also be used with arc welding machines. Next, examples of the present invention will be shown together with comparative examples. The tensile strength, elongation %, and hardness of each welding rod having the composition shown in Table 1 were measured, and the results are also shown in Table 1.
本発明の溶接棒は、TIG溶接法、MIG溶接法
及びアーク溶接法に適用でき、また鋳鉄、強じん
鋳鉄、工具鋼などへも溶接可能で適用範囲が広
く、且つ、溶接後の硬度のバラツキもなく、溶け
具合が良好で作業性に優れている。
The welding rod of the present invention can be applied to TIG welding, MIG welding, and arc welding, and can also be used to weld cast iron, strong cast iron, tool steel, etc., and has a wide range of applications, and has no variation in hardness after welding. It melts well and is easy to work with.
