AK-ERCuAl-A1 (TIG / MIG)
Standard:
EN ISO 24373 CuAl7
AWS A5.7 ERCuAl-A1
GB/T 9460 CuAl7
Application: Especially suitable for welding carbon steel and stainless steel. The fluidity of the molten metal is good, the weld shape is beautiful, and it is also suitable for butt welding of steel and copper. Applied to shipbuilding and machinery manufacturing, it is recommended to use pulsed argon arc welding when welding multi-layer steel interlayers.
