WELDING
All repairs in this manual require the use of a Metal-Inert Gas (MIG) welder, Gas (oxyacetylene) welding must not be used.
Both high strength steel and mild steel can be welded using the MIG welder. The I-CAR recommendations for welding should
be followed. The shielding gas should be 75% Argon and 25% CO
2
.
The recommended welding wire size is 0.23" and the wire should satisfy the American Welding Society standard code
AWSER70S-6.
During the repair process, plug welds are used to duplicate original factory spot welds. All plug welds should be done with the
MIG welder. An 8 mm (5/16") hole is placed in the top (welding side) sheetmetal.
You then begin welding along the edges and the spiral towards the center (see illustration). This is important so that weld
penetration between the two metal pieces takes place along the circumference of the circle.
Observe the following tips when welding.
1.
Wear appropriate eye protection.
2. Carefully follow the manufacturers operating instructions for the welding machine you are using.
3. Do not weld, smoke or allow open flames around volatile chemicals, cleaners or solvents or in any area where they have
just been used.
