Welding Copper And Brass. Click to see full answer. Filler metals are available although these are generally based on copper-silicon or copper-tin alloys due to the problems of transferring zinc across the welding arc.
The generation of zinc fume results in welds which are likely to be porous and consequently unacceptable particularly if autogenous welding is attempted. There is no defect of copper welds attained heat input below 400800rpm of rotational and travel speed 50mmmin. Since these metals have different melting points considerable care must be exercised in welding not to change the characteristics of the metal too much by burning out these alloys.
