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 steels and low alloy steels, such as vehicles, engineering &
construction machinery, bridges, containers and so on.
