Installation Preparations
Installation PreparationsApplication of weld-through primer
For treatment against corrosion, remove the paint grease, and other material from the portion of the new part and body to be welded, and apply weld- through primer.
Making holes for CO(2) arc welding
For places that cannot be spot welded, make a hole of 5 - 6 mm {(0,20-0.24 in} for CO(2) arc welding using a punch or drill.
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.
Rough cutting of new parts
For cut-and-join areas, allow for an overlap of 30-50 mm (1.18-1.97 in} with remaining area in a body side and then rough cut the new part.
