WebThe following points highlight the five main types of resistance welding. The types are: 1. Spot Welding 2. Projection Welding 3. Seam Welding 4. Butt Welding 5. Percussion Welding. Type # 1. Spot Welding: This is probably the simplest form of resistance welding and best suited for ordinary sheet steel. For obtaining good welds having strength, and … WebTack welds are often used to hold parts in place while more extensive, final welds are made. For sheet metal, tack welds often provide more than adequate strength and avoid the over design and expense of an “all-around” fillet weld. However, if no other welding is required on an assembly, spot welding deserves initial consideration.
