Mild Steel Plate (Ni Plating) + Aluminium Alloy (ex. Duralumin)

Weldability of the material and electrode material (guideline)

Weldability Very bad
Upper Electrode Cu-Cr-Zr (Equivalent to RWMA-2)
Lower Electrode Cu-Cr-Zr (Equivalent to RWMA-2)
Special Note Not enough welding strength.
Flat electrode to prevent deforming.
