ERCuAl-A1 Welding Wire

ERCuAl-A1 Welding Wire

1. Application

ERCuAl-A1 Welding Wire is especially suitable for the welding of carbon steel and stainless steel. The molten metal has good fluidity and beautiful weld bead formation, and is also suitable for butt welding of steel and copper. Used in shipbuilding and machinery manufacturing. Pulsed argon arc welding is recommended for multi-layer steel sandwich welding.
