The spot welding process tends to harden the material, causing it to warp. This reduces the material''s fatigue strength, and may stretch the material as well as anneal it. The physical effects of spot welding include internal cracking, surface cracks and a bad appearance. The crack around the weld nugget will be extended under an external load or fatigue to produce a different type of failure. The chemical properties affected include the metal''s internal resistance and its corrosive …

9.5 Seam welding. Seam welding uses a wheel-shaped electrode (Fig. 9.4) to make either a series of overlapping spot welds to form a continuously welded and leak tight seam or a number of spot welds spaced apart – roll-spot welding. The requirements on electrodes and surface finish are the same as for spot welding.
In achieving a perfect weld, a range of variables come into play: Electrode Force: Dictates the quality of the weld. Squeeze Time: The lull between applying force and initiating the current. Welding Time: The span during which the current actively flows. Holding Time: Period for the nugget to solidify.
