FW CuSi-A
AWS: SFA 5.7: ERCuSi-A
EN ISO CODE:
FW CuSi-A is a solid wire for TIG welding, available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. This filler metals are copper-base alloys containing approximately three percent silicon. It is for welding of copper-silicon and copper-zinc base metals, to themselves and also to steel. Generally, it is best to keep the weld pool small and the interpass temperature below 65 C to minimize hot cracking. Welding can be done in all positions, but the flat position is preferred.
