filler metals
Steels are usually welded with a filler alloy made specially for the purpose. To prevent rusting in storage, these wires are often lightly copper plated. With electric arc welding, a major use for the filler rod is as a consumable electrode that also generates heat in the workpiece.

Can I braze copper to copper?

Both oxygen-bearing and oxygen-free copper can be brazed to produce a joint with satisfactory properties. The full strength of an annealed copper brazed joint will be developed with a lap joint. The flame used should be slightly carburizing. All of the silver brazing alloys can be used with the proper fluxes.
