Types of Welding

(OFW) Oxy-Fuel Welding (Gas Welding/Oxy-Acetylene Welding)

Oxy-fuel welding (OFW) is also known as Gas welding or Oxy-fuel gas welding. The term ‘Oxy-fuel’ is used to denote a combination of Oxygen and a Fuel gas, means it’s a process in which Oxygen and a fuel (combustible gas) both are required. Most commonly used fuel gas is Acetylene and thus the name Oxy-Acetylene …

(SAW) Submerged Arc Welding

Submerged Arc Welding (SAW) is an arc welding process in which arc is generated between a bare electrode and the workpiece. The arc and the molten weld pool are submerged in a blanket of granular fusible flux on the workpiece. Flux covers the arc and prevents fumes, sparks, spatter, and intense ultra violet radiation from …

(FCAW) Flux Cored Arc Welding

Flux cored arc welding (FCAW) is a welding process that uses the heat produced by an arc generated between a continuous tubular filler metal (electrode) and the work piece. The filler metal is hollow with flux at the core. Flux present at the core of the filler metal shields the molten weld pool from atmospheric …

Gas Metal Arc Welding (GMAW)

Gas Metal Arc Welding (GMAW) is also known as Metal Inert Gas Welding (MIG welding). In this process, consumable electrode is used in the form of wire and an inert gas such as Argon, Helium, Carbon dioxide or a mixture of them are used. These inert gases shield the weld pool from atmospheric contamination. The …

Shielded Metal Arc Welding (SMAW)

Shielded Metal Arc Welding (SMAW) also known as Manual Metal Arc Welding (MMAW) is a manual arc welding process that uses a consumable electrode (covered with a flux). Electrode is connected with one terminal of the power source and the work is connected with the other terminal of the power source. Welding cable (or lead) is used for this purpose. …

Types Of Welding – Classification of welding processes

Welding is a process of permanently joining two or more parts by the application of heat and (or) pressure. As per American Welding Society 50 different welding processes available today; some are very popular among the industries such as SMAW, GMAW, GTAW, SAW, FCAW etc. whereas some are very specific and limited to few industries …
