Equipment: Set up the equipment as directed by the manufacturer. The hoses must be untwisted. The core must
be free of abraded rod particles. The gas and current nozzles must be free of slag and scale residue. Pay
attention to the quality of the welding wire and the throughput of gas.

Body: Ensure that the joint surface is correct. Prepare a bare metal joint surface. Maintain the correct gaps
(formation of roots).

Notes on technique/method: NOTE :
NOTE :
Attach the ground cable right next to the welding point (ensure that good contact is made). During plug welding
start welding on the lower panel to ensure adequate penetration.

Plug welding
Bonded glazing
The windscreen, side and rear windows are bonded directly onto the window frames on the body and
liftgate.
The windows are bonded primarily for reasons of adhesive strength. Bonded glazing provides additional
torsional stiffness to the body.
The increased application of heat during MIG welding destroys the welding primer/zinc layer over a much
larger area than during resistance spot welding, as a result of which much more care needs to be taken
when applying anti-corrosion protection afterwards.
A test weld should always be carried out to ensure that the welded joint is not just a surface connection.
