Welding Projection Spot. Spot welding is a way of joining a metal surface by the heat obtained from resistance to current. The technique is also limited to Charpy-type specimens.
In spot welding one or more projections are attached to one or two attached work pieces. Spot welding is different from projection welding. DS310 Spot Projection Welding Panel.

The projection welding process is similar to spot welding except that the welding pressure and welding current. Projection Welding In Projection welding size and shape of individualwelds are determined by the presence of projectionsembossments or intersections on the metals to bejoined. Projection welding has fewer variables that affect the resistance welding process as compared to spot welding. Mid Frequency AC MFAC Spot plus Projection Welding Machine.
