WELDING TSB Revision BASE OF BODY REPAIR 9-5 NOTES REGARDING WELDING 1. Selection of the electrode tips • Select the electrode tips according to the thickness of the panels to be welded. • The angle of the tip should be between 90 degree angle and 120 degree angle. • To always keep the end of tip in the correct shape, use a tip cutter, file or similar tool to 2. Alignment of the electrode tips • Adjust the arms so that the upper and lower electrode tips are in a straight line. 3. Alignment and length of the arms • Adjust the electrode tips so that the upper and lower arms are parallel. • Select an appropriate arm length. Note, how- ever, that the arm length should not be more 4. The weld points • The overall strength will increase as the pitch decreases; however, if the pitch decreases • Make the spot welds at the center of the flanges to provide sufficient adhesion. When • The number of spot weld points should be the same as, or slightly more than the number of • When spot welding three or more panels together, if painted surfaces cause a loss of .
