Installation Preparations

INSTALLATION PREPARATIONS

Application of Weld-through Primer




- For treatment against corrosion, remove the paint grease, and other material from the portion of new part and body to be welded, and apply weld-through primer.

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(2) Arc Welding




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




- 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.

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.
