Welding processes such as Gas Metal Arc Welding ('GMAW') and Gas Tungsten Arc Welding ('GTAW') are commonly used for welding copper and its alloys, since high localized heat input is important when welding materials with high thermal conductivity.
Is copper good for welding?
Joining Copper to Copper or to Copper Alloys. Copper and most copper alloys can be successfully joined using welding, brazing or soldering processes. ... Hard soldering involves heating the filler materials to a much higher temperature, so the joint will be a lot stronger than other soldered joints.Oct 15, 2015
