Rough Cutting of New Parts
• For cut-and-join areas, allow for an overlap of 30—50 mm {1.2—1.9 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 CO

Arc Welding
• For places that cannot be spot welded, make a hole for CO
2
arc welding using a punch or drill as follows.
(mm {in})
• Grind the shaded section indicated in the diagram below and create a hole in the part where the 3—4 plates
are put together. Also, weld the plates together tightly so that gaps do not develop.
