15. WELDING PROCESSES

16. SPOT WELDING
Spot welding is one of the oldest welding processes. It is used in a wide range of industries but notably for the assembly of sheet steel vehicle bodies. This is a type of resistance welding where the spot welds are made at regular intervals on overlapping sheets of metal. Spot welding is primarily used for joining parts that are normally up to 3 mm in thickness.

17. SPOT WELDING

18. MIG WELDING
Gas Metal Arc Welding (GMAW) is frequently referred to as MIG welding.  MIG welding is a commonly used high deposition rate welding process.  Wire is continuously fed from a spool.  MIG welding is therefore referred to as a semiautomatic welding process.

20. PROJECTION WELDING
Projection welding is a variation of spot welding. Projections are designed in one part. These act as current concentrators for the welding process. When the two parts are mated together, these projections are the high points that first make contact. As the power is cycled, the projections simultaneously carry the current and are welded.
Due to the efficiency of power transfer, thicker materials can be successfully welded. Materials as thick as 3 mm (0.125 in) can be successfully welded.
Low carbon steels, low alloy steels, stainless steels, as well as aluminum can be welded using this process.
Projections are usually semi-spherical or blunt conical type.
Projection welding requires that the height of projections be controlled to within a range of mm (0.003 in).
