Welding is one age old joining process that can efficiently and economically assemble two or more structural members permanently. There exist a large variety of welding processes that can join structures of various materials in multifarious ways. Gas Tungsten Arc Welding (GTAW), popularly known as Tungsten Inert Gas (TIG) welding, is one of the fusion welding processes where metals can be joined by coalescence or weld bead formation due to

Tungsten Inert Gas (TIG) welding is one popular arc based welding process where electric arc is constituted between a non-consumable tungsten electrode and the workpiece. It is one reliable and economic process to efficiently and permanently join metallic parts with or without the usage of filler metal. Apart from its capability of producing sound joints, splendid weld bead appearance makes this process overwhelmingly acceptable in various applications ranging from structural
