Rough Cutting of New Parts

• For cut-and-join areas, allow for an overlap of 30—50 mm {1.18—1.97 in} with the remaining area on the body side and then rough-cut the new parts.

Determination of Welding Method

• If the total thickness at the area to be welded is 3 mm {0.12 in} or more, use a CO 2 gas shielded-arc welder to make the plug welds.

Making Holes for CO2 Arc Welding

• For places that cannot be spot welded, make a hole for CO 2 arc welding using a punch or drill as follows.
