Débrasage Unbrazing
Soudure par points de chaînette sous gaz de protection MAGNota Chain spot welding under MAG shielding gas

Note: for good weld quality, it is recommended to use a gas composed of Argon + 15% CO2, which is considered an active gas (MAG).

Soudure par point de résistance électrique Electrical resistance spot welding
Soudure par bouchonnage Plug welding
Under MAG shielding gas
Sertissage des panneaux extérieurs de porte Crimping of outer door panels
Sigle de sécurité Safety symbol
Indicates that the welding operation in progress concerns one or more safety components of the vehicle.
Glacis d’étain Tin coating
Hot-air torch

NOTE: the tin coating largely compensates for the risk of heat distortion caused by welding.

Application de mastic électrosoudable Application of weldable sealer
This conductive sealer is placed between two sheets to be spot welded. It provides sealing between the sheets and prevents corrosion of the spot welds.
Application de peinture à base d’aluminium Application of aluminium-based paint
It must be applied to the joining faces of each part to be plug welded. This paint conducts current and resists high temperatures; it provides anti-corrosion protection around the spot welds.
