General notes on spot welding of aluminum parts - AH60.00-P-0017-01N

Model 215 

The equipment present in MB workshops for spot welding sheet steel can be used for sheet aluminum only under certain conditions. For this reason, always observe the following repair method for spot welding sheet aluminum.

• Grind spot welding flanges down to bare metal on both sides with a CrNi wire brush.
• Attach the V2A sheet metal strips (non-rusting CrNi steel) contained in the aluminum workshop cart to the spot welding flanges with insulated clamps.

Optimum, sturdy welds are possible only with this repair method. 

When purchasing a new spot welder, always ensure that it is capable of spot welding aluminum.

Approvals and recommendations are given in the MB workshop equipment catalog.
