Welding In Body Components

Once the spare parts have been secured, repair spotwelds must be placed on the old spotwelds because there is no current flow possible in areas with a hardened bonded layer.

Spot-welding body components

Welding procedures other than resistance spot-welding are not permitted since the thermal effect would destroy the bonded joint over a wide area.

Information 

• In areas in which bonded flanges are spot-welded in an unhardened state, suction devices must be used due to combustion products  .
• Areas that can only be accessed from one side must be joined with MAG plug-welds or MAG welded seams. In these cases, no adhesive can be used in the vicinity of the welded seam because this would burn and would have a negative effect on the joint  .
• The areas without adhesive must be protected using appropriate anti-corrosion and sealing measures  .
