WebSoldering vs. back casting. The spot welding winner is clear! The advantages of our back-cast electrodes at a glance: ... Projection welding is a version of spot welding. In this process, the weld is made at raised sections (projections) on one or both of the components to be joined. Heat is generated in the same way as with spot welding ... WebSpot welding is particularly useful for corners and thin materials. Projection welding is more useful for thick metal materials and products that require an exceptionally strong weld, since less heat and pressure during the welding process yield a stronger joint.
