WELDING PROCESSES
The welding processes are not the scope of this manual, specific for welding inspections. However, only for refreshing, the most common arc welding processes used in heavy and medium carbon and alloy steel manufacturing are: SMAW: Shielded Metal Arc Welding – stick welding electrode; GMAW : Gas Metal Arc Welding or MIG welding – solid wire or metal cored wire; GTAW : Gas Tungsten Arc Welding or TIG welding – rod or solid wire. SAW : Submerged Arc Welding – solid or tubular wire; FCAW : Flux Cored Arc Welding – gas-shielded flux cored wire; CAW : Carbon Arc Welding PAW : Plasma Arc Welding welding work types of welding processes The steels commonly used in plate manufacturing, metallic structures and piping systems are covered by the specifications of ASTM, AISI, ASME, SAE, and API. The specifications often refer to the same types of steels, although different restriction s on the chemical analysis and mechanical properties. Commonly the most ...
