What is Submerged Arc Welding?Submerged arc welding (SAW) is a welding process that involves the formation of an electric arc between a continuously fed electrode and the workpiece to be welded. The process of submerged arc welding was developed by the Linde-Union Carbide Company.SAW requires a continuous fed of consumable ... Read More

What is Resistance Heating?When the heat is produced by passing electric current through the resistance of a conductor, it is called electric resistance heating (ERH). This method of electric heating is based on the principle of I2R loss. If ‘P’ is the electric power developed in the heating circuit and ... Read More

What is Plasma Arc Welding?Plasma arc welding (PAW) is a welding process in which the electric arc is formed between an electrode and the workpiece. The electrode used in the plasma arc welding is usually but not always made of sintered tungsten. The process of plasma arc welding was discovered ... Read More

The type of electric welding in which an arc is established between the workpiece and the filler metal electrode is known as metallic arc welding or simply metal arc welding.The figure shows the simplified circuit diagram of metallic arc welding.In metallic arc welding, the intense heat of the arc forms ...

Induction heating is the process of heating the materials which are electrically conductive by electromagnetic induction like metals.Working Principle of Induction HeatingInduction heating makes use of the induced current by the electromagnetic induction in the charge to be heated. The induction heating works on the principle of transformer action, in ... Read More

What is Gas Tungsten Arc Welding?Gas tungsten arc welding (GTAW) is an electric arc welding process which uses a non-consumable tungsten electrode to produce the weld. The gas tungsten arc welding is also known as tungsten inert gas (TIG) welding.In case of GTAW, the weld area is protected from the ... Read More

What is Gas Metal Arc Welding?Gas metal arc welding (GMAW) is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. The gas metal arc welding is also known as metal inert gas (MIG) welding ... Read More

Electron Beam WeldingElectron beam welding (EBW) is a welding process in which a beam of high velocity electrons is applied to the materials being joined or fused. When these high velocity electrons impact the workpieces, the kinetic energy of the electrons is transformed into heat, which melts the workpieces.The first ... Read More
