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

resistance spot welding process parameters on the shear-tensile strength of the welded joints of Inconel alloy 625 was investigated. Experimental study using full factorial design of the welding current‚ welding time‚ and electrode force parameters was conducted. In order to identify the influence of each parameter and their interaction a general linear model and a second order model using response surface method was developed. Nonlinear correlation was observed between the welding process parameters

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

States alone there was 360‚000 welders in 2012 and by 2022 there is supposed to be a 32% increase. This will create many more jobs for future welders. The process of becoming a welder varies on what type of welding you want to become certified in. There is many types of welding including mig‚ tig‚ arc‚ and others and for each type there is diffrent ways to do each one. Along with learning how to use the welders‚ you’re going to have to know how to use other machines like sanders‚ grinders‚ plasma cutters

reported that the use of pulsed arc welding in place of conventional GTAW increases the output by 200–400%‚ reduces consumption of argon by three to ten times‚ and also reduces the cost of 1 m weld deposition by three to five times. The aim of pulsing is mainly to achieve maximum penetration without excessive heat build-up‚ by using the high current pulses to penetrate deeply and then allowing the weld pool to dissipate some of the heat during relatively longer arc period at a low current. The

PROS AND CONS OF UNDERWATER WELDING To briefly present the advantages and disadvantages of underwater welding let us first separate this two compound words‚ the UNDERWATER and WELDING. Underwater is anywhere where this is water‚ either in low or in deep aquatic areas. Now‚ Welding is the action of burning something (particularly a metal) into creating or fixing something with the use of a high temperature to burn down or melt a metallic material so that it can be reformed. Combining this two concepts
