Overview I-6
Installation Preparations
Use of welding primer
To prevent corrosion, remove the paint, grease
and other substances from new parts and welding
portions and then apply welding primer.
Determination of welding methods
If the overall thickness of weld points is higher
than or equals to 3mm(0.12in), adopt CO2
shielded welding for rivet welding.
Drilling for CO2 shielded welding
For the locations in which the spot welding can’t
be adopted, drill a hole with drilling machine or
hand-held drilling machine for CO2 shielded
welding.

Grind the hatched portion shown in the figure below,
drill a hole on 3~4 pieces of metal panels stacked
together, and weld tightly together these metal
panels, in order to eliminate the further development
of gap.
Rough Cutting of New Parts
For cutting and splicing portions, leave
overlapping parts of 30~50mm {1.18~1.97in} on
the body side and then roughly cut the new parts.
