Welding In Body Components

WARNING: This page is about a different car, the 2018 Porsche Macan. However, it is still accessible from the selected car via links, so may be relevant.

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

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 .

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