Fusion welding is a joining process that uses fusion of the base metal to make the weld. It is the most widely used joining process. Four major types of fusion welding processes will be discussed: gas welding, arc welding, high‐energy beam welding, and resistance spot welding. These processes are listed as follows:

1 (a) Gas welding:Oxyacetylene welding (OAW)

2 (b) Arc welding:Shielded metal arc welding (SMAW)Gas−tungsten arc welding (GTAW)Plasma arc welding (PAW)Gas−metal arc welding (GMAW)Flux‐cored arc welding (FCAW)Submerged arc welding (SAW)Electroslag welding (ESW)

3 (c) High‐energy beam welding:Electron beam welding (EBW)Laser beam welding (LBW)

4 (d) Resistance spot welding:Resistance spot welding (RSW)

There is no arc in ESW except during initiation of the process. For convenience of discussion, however, it is grouped with arc welding processes.
