Copper alloys have quite different welding characteristics due to differences in thermal conductivity. For example copper, due to its high thermal conductivity, may require substantial preheat to counteract the very high heat sink.

Can copper be welded?

Copper and Copper alloys are important engineering materials because of their good electrical and thermal conductivity, corrosion resistance, metal-to-metal wear resistance and distinctive aesthetic appearance. Copper and most copper alloys can be joined by welding, brazing, and soldering.

Is it difficult to weld copper?

Copper welding is not hard. The heat required for this type of welding is approximately twice that required for steel of similar thickness. Copper has a high thermal conductivity. ... Copper may be welded with a slightly oxidizing flame because the molten metal is protected by the oxide which is formed by the flame.
