Resistance Spot Welding
Resistance spot welding must primarily be used if the capacity of the welding equipment is matched to panel thickness. When carrying out resistance spot welding, grind down to bare metal.
Clean the surfaces with Scotch-Brite or similar to minimize zinc and phosphating damage. Apply welding primer between the panels.
NOTE:
Always test weld in accordance with the method below. Always set the weld according to panel quality
