Projection welding is actually a modification of spot welding the pioneer resistance welding process. Projection welding is generally used for projects with thicker materials around 0035 and thicker. Embossed projection welding uses projections worked on the base material to concentrate current flow on the projections.
Projection welding is actually a modification of spot welding the pioneer resistance welding process.
Practical applications include welding gas tank reinforcements shock absorber brackets and oil filters. The main difference with the Press Spot welders vs the Projection style welders is the lower knee. Projection welding is a good option when multiple spot welds have to be made in reasonably close proximity at predetermined locations. Unlike embossed projection welding solid projection welding does not use projections.
