Its most common applications are for aluminum and stainless steel. No flux is used no slag entrapment in the weld metal. Address any site specific risks and add them to your SWMS Template. But our main focus in this welding procedure discussion is related to metallic welding. Tungsten inert gas (TIG) welding became an overnight success in the 1940s for joining magnesium and aluminium. The weld joint configuration adopted was a close contact butt joint with no joint gap, as illustrated in Fig. There are different types of welding done but most common Welding Types are Arc Welding, Oxyfuel Gas Welding and Resistance Welding. <> The semicircular deposits on the weld head are called : 8. Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium).A filler metal is normally used, though some welds, known as autogenous welds, or . Don't take that sort of risk - we can help). MIG welding is more popular than TIG welding because of its diverse capabilities and ease. welding parameters on TIG welding of Aluminum plate" is based on my own work carried out during the course of my study under the supervision of Dr. M.

Throughout most of the industries that employ metal construction, the processes of MIG, TIG and stick welding are the most widely used due to the power, efficiency and versatility of each method. TIG welding utilizes a tungsten welding electrode, a filler metal rod and an inert gas to shield the weld. Tig Welding: This type of welding is also known as tungsten inert gas TIG welding which is also an an arc welding process that uses a non-consumable tungsten electrode to produce the weld. What I mean by welding process is that; there are different types of welding processes such as SMAW, GTAW or TIG, GMAW, SAW and many others but in domestic construction domain you will be exposed mainly to SMAW and GTAW, if you are fabricating spools at workshop then GMAW is quicker than GTAW, hence, both of them they use gas as Backing but in .
