(a) PRE-WELDING MEASUREMENTS
(1) Always take measurements before installing under-body or engine components to ensure correct assembly. After installation, confirm proper fit.
(1) The number of welding spots should be as follows.
Spot weld: 1.3 X No. of manufacturer's spots. Plug weld: More than No. of manufacturer's plugs.
(2) Plug welding should be done with a MIG (Metal Inert Gas) welder. Do not gas weld or braze panels at areas other than specified.
(c) POST-WELDING REFINISHING
(1) Always check the welded spots to ensure they are secure.
(2) When smoothing out the weld spots with a disc grinder, be careful not to grind off too much as this will weaken the weld.
(d) SPOT WELD LOCATIONS
(1) Avoid welding over previously welded areas.
(e) SPOT WELDING PRECAUTIONS
(1) The shape of the tip point of the spot welder significantly affects the strength of the weld. Therefore, maintain the tip point in the proper shape, and allow it to cool after every five or six spots.
(2) Completely remove the paint from the areas to be spot welded, including the seams and the surfaces that come in contact with the welding tip.
(3) Use a sander to remove any burrs that are created during spot welding.
