- Cutting out part by grinding off flange
or grinding back remaining traces of
spot weld.
- Finish surface after welding.
- Angle grinder equipped with a rubber
pad and a 120 to 180 mm diameter
fibre disc grain size P36. Chiselling
Grind back beads or spot welds.
Straight grinding wheel with 75 mm
diameter bakelite impregnated disc,
thickness 1.8 to 3.2 mm.
Grind back spot welds.
20 000 rpm straight grinder with 10 or 16
mm diameter spherical burr.
Drill spot welds.
Hardened steel bit. Speed of rotation 800
to 1 000 rpm.
Unpicking
Cleaning surfaces to be welded.
100 mm diameter fibre disc.
Cutting with a saw.
Pneumatic power hacksaw.
Unsoldering.
Plug welding.
Under MAG gas protection.
Crimping of exterior door panels.
Safety symbol.
This means that the welding operation
in question concerns one or more of the
vehicle’s vital safety components.
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.
Application of weldable mastic.
This mastic conducts electricity, applied
between two panels to be spot welded,
it ensures the seal between the panels
and avoids corrosion of the spot welds.
Application of aluminium paint.
This is to be applied to the joint faces of
each of the parts to be plug welded.
The paint conducts electricity and is is
resistant to high temperatures. It
provides anti-corrosion protection
around the plug welds.
Apply a fillet of extruded mastic
• from a manual or pneumatic spray
gun.
• one or two pot mastic for crimped
and butt joints.
Spray on sealer
• spray gun.
• two pot anti-gravel and anti-
corrosion mastic.
MAG stitch weld
Note : to obtain a good quality weld we
recommend the use of a gas consisting
of argon + 15 % CO2. This is
considered to be an active gas (MAG).
