E3

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

Guideline of the Weldability of the Material and Electrode Material

Weldability Very Difficult
Upper Electrode Cu-Cr-Zr (Equivalent to RWMA-2)
Lower Electrode Cu-Cr-Zr (Equivalent to RWMA-2)
Special Note

Not enough welding strength.

Flatten electrode to prevent deforming.
