Metal Welding - Types and Processes Welding. So you think it’s as simple as grabbing the gun and pulling the trigger‚ eh? Tell me this then - what types of welding are there? Not completely sure? Read on... Arc Welding Arc welding is a process utilizing the concentrated heat of an electric arc to join metal by fusion of the parent metal and the addition of metal to joint usually provided by a consumable electrode. Either direct or alternating current may be used for the arc‚ depending upon

What is MIG Welding? Metal Inert Gas (MIG) welding‚ also sometimes called Gas Metal Arc Welding (GMAW) is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding gun. A flow of an inert gas‚ originally argon‚ is also passed through the welding gun at the same

Arc Welding or SMAW Generally known as stick or arc welding. Arc welding is the most basic of all welding types‚ is easy to master in a home welding situation. Stick welding can be used for manufacturing‚ construction and repairs‚ very much well suited for heavy metal size 4 millimetres upwards. Thinner sheet metals and alloys are usually more suited to the mig welding types. STEPS: 1. Gather your materials. You should have a welding machine‚ electrode holder with lead‚ ground clamp with lead‚

Underwater welding‚ Underwater welding was invented in Russia in 1932 by Konstantin Konstanovich Khrenov and used it throughout the soviet navy. During WWII‚ the American Cyril D. Jensen‚ professor of engineering at Lehigh university‚ developed the USA’s own underwater welding programs and created 2 U.S. patents in the field. (Agnew‚ 1999-2013) Under water is a technique that is employed in various engineering projects‚ where in welding is carried out under the surface of the water. Underwater
