How Do You Perform a Spot Weld on a Joint?

Posted: July 2, 2014 By: Louis Beaudreau

Using a stitch welder to spot weld two pieces of metal together is useful when you have one piece with round holes in it that needs to be welded to another flat piece underneath. If you drill holes in one of your metal panels, clamp it completely flat over the other panel you want to weld it to. You should be able to see the base metal through the holes in the top panel. Too spot weld this joint together, simply place the electrode in each of the holes. Since the rod is arcing on the inner metal panel, complete penetration is assured.

Now, all you have to do is simply fill in the panel holes with weld forming a “spot.” Remember that the best way to prevent burn through is to minimize the gap between each panel as much as possible. As always practice spot welding with your stitch welder electrode on drilled pieces of scrap metal before attempting to perform one on your vehicle.
