Description:
CHW-50C
is a coppered
low alloy steel wire with all position welding. The wire has a very good
performance and has a large range of current for welding. The weld metal
shows lower temperature impact toughness. It is suitable for butt and fillet
structures made by mild steel and low alloy steel, such as vehicles,
engineering & construction machineries, bridges, containers, etc.
