WarningBefore any work on the structure of a vehicle with on board electric energy (electric vehicle/hybrid vehicle), the vehicle must be isolated by an authorised technician
WarningObserve the safety and cleanliness recommendations
WarningObserve the precautions to be taken for the pre-tensioning components
WarningAny repair work carried out on a vehicle with on board electric energy (electric vehicle/hybrid vehicle) must be carried out by an authorised person
WarningAll of the stripped surfaces must be protected by means of the approved electrolytic rezincing process
WarningThe number of spot welds necessary for the assembly of a new part must be identical to the number of spot welds fixing the original part

Replacement part preparation
WarningWhen cleaning the mating edges, use scouring wheels only to avoid damaging the anticorrosion protection
Preparation: windscreen pillar
Mark then drill to diameter 6,5 mm (or 8 mm for the heavy thicknesses) for later plug welding
Prepare the mating edges and protect them using a weldable primer (index "C7")
Apply the weld-through primer on the internal faces of the panels to be welded
Cutting of the part on the body
Cut out the spot welds
Cut out the spot welds
Remove the windscreen aperture pillar
Cleaning and preparation of the body
Prepare the mating edges and protect them using a weldable primer (index "C7")
NoteApply the weld-through primer on the internal faces of the panels to be welded
Adjustment
Position
- The windscreen pillar (1)
- The components for adjusting
Holds the part in position
Welding
WarningThe number of spot welds necessary for the assembly of a new part must be identical to the number of spot welds fixing the original part
Weld with electric spot welds
Weld with electric spot welds
MAG plug weld (at "a")
Grind the MAG plug weld
Weld with MAG plug welds
Grind the MAG plug welds
Sealing protection
Apply a phosphate-print layer to the zones laid bare
Apply a sealing mastic (index "A1")
Painting, then spraying of the index "C5" product into the hollow sections in the repair zone
Additional operations
Refit the electrical harnesses and the components removed
Reinitialisation
Reactivate the pyrotechnic systems
WarningPerform the operations that are required following a reconnection of the ancillaries battery
Reconnect the ancillaries battery
