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

Electric WeldingThe process of joining materials together through the use of heat that is produced by an electric current is known as electric welding.Electric welding is often done by melting the workpieces by the heat produced by electric current and adding a filler material to form a pool of molten ...
