Chiselling Crimping of exterior door panels.
Grind back beads or spot welds.
Straight grinding wheel with 75 mm
diameter bakelite impregnated disc,
thickness 1.8 to 3.2 mm.Safety symbol.
This means that the welding operation in
question concerns one or more of the
vehicle's vital safety components.
Grind back spot welds.
Straight grinding wheel 20 000 rpm fitted
with a spherical burr Ø 10 or 16 mm.Body solder - lead fill.
Hot air torch.
Nozzle output temperature 600° min.
Slipper+ 33 % tin solder + tallow.
Note: to a large extent, body solder filling
compensates for the heat distortion
caused by welding. Drill spot welds.
Hardened steel bit.
Speed of rotation 800 to 1 000 rpm.
Unpicking
Application of weldable mastic.
This mastic is a conductor, interposed
between two spot welding sheets, it
ensures the seal between the sheets and
avoids corrosion of the spot weld Cleaning surfaces to be welded.
Fibre disc Ø 100 mm
Cutting with a saw.
Pneumatic power hacksaw.
Application of aluminium paint.
This is to be applied to the joint faces of
each of the parts to be plug welded. This
paint is conductive and can withstand high
temperatures; it gives anti-corrosion
protection around welds –Cut out part by grinding off flange or
grinding back remaining traces of spot
weld.
–Finish surface after welding.
–Angle grinder fitted with a rubber pad
and a 120 to 180 mm diameter fibre disc
grain size P36.
Unsoldering.Apply a fillet of extruded mastic
●from a manual or pneumatic spray gun
●one or two pot mastic for crimped and
butt joints.
MAG stitch weld
Note: to obtain a good quality weld we
recommend the use of a gas consisting of
argon + 15% CO2 which is considered an
active gas (MAG)Apply mastic by spraying
●spray gun.
●anti-chipping and anti-corrosion in two
parts
Apply a bead of extruded adhesive mastic
●from a manual or pneumatic spray gun
●adhesive mastic in one or two parts Resistance spot welding
