Plasma arc welding (PAW) is an arc welding process in which the heat required for welding is generated by a constricted arc between a non-consumable electrode and the workpiece. Plasma Arc Welding is essentially an extension of Gas Tungsten Arc Welding (GTAW). Like GTAW, a non-consumable electrode is used in Plasma Arc Welding (PAW). However, […]

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

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

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 Tungsten Arc Welding (GTAW), commonly known as TIG Welding, is a highly precise welding method that utilizes a non-consumable tungsten electrode. This technique is favored across various industries, including aerospace, automotive, and construction, for its ability to produce high-quality welds. In this guide, we will explore the fundamentals of TIG welding, its components, advantages, limitations,

MIG welding or Metal Inert Gas Welding is also known as Gas Metal Arc Welding (GMAW). In MIG welding process, consumable electrode is used in the form of filler wire and a shielding gas such as Argon, Helium, Carbon dioxide or a mixture of these gases are used. These gases shield the molten weld pool

Shielded Metal Arc Welding (SMAW) is also known as Manual Metal Arc Welding (MMAW) or stick welding. It is a manual arc welding process that uses a consumable electrode (covered with flux). The electrode is connected with one terminal of the power source and the work is connected with the other terminal of the power

Welding is a process of permanently joining two parts (permanent fusion) by the application of heat and (or) pressure. Filler metal may be added to the joint depending on the welding process and the type of joint. The American Welding Society (AWS) has recognized more than 50 different types of welding processes, some of them are
