Welding Metallurgy
Chapter One
Fusion Welding Processes
Fusion welding processes will be described in this chapter, including gas
welding, arc welding, and high-energy beam welding. The advantages and disadvantages
of each process will be discussed.
1.1 OVERVIEW
1.1.1 Fusion Welding Processes
Fusion welding is a joining process that uses fusion of the base metal to make
the weld. The three major types of fusion welding processes are as follows:
1. Gas welding:
Oxyacetylene welding (OAW)
2. 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. High-energy beam welding:
Electron beam welding (EBW)
Laser beam welding (LBW)
