Stitch welding

Here, a series of overlapping spot welds are made with the spot welding machine using the conventional electrode tip. Both water tight and gas tight joints can be made using this process. With this process, welds of the same quality as that by using seam welding can be attained. This is more advantageous than seam welding in the sense that it can be used with irregular and awkward type jobs, where a wheel type electrode cannot enter. The stitch welding is much slower than seam welding.
