Metal Inert Gas Welding Pdf

Metal Inert Gas Welding Pdf. Shielding gases are inert or semiinert gases used in gas metal arc welding and gas tungsten arc welding to protect the weld area from oxygen and water vapour which can reduce the quality of the weld or make the welding more difficult Gas metal arc welding (GMAW) or metal inert gas (MIG) welding is a process that uses a continuous wire feed.

PDF fileabbreviation of Tungsten Inert Gas Tungsten also called wolfram is a metal with a fusion point of more than 3300oC which means more than double the fusion point of the metals which are usually welded Inert Gas is the same thing as inactive gas which means a type of gas that will not to combine with other elements In Germany this method is called WIG welding the W.

Gas blending Wikipedia

Gas metal arc welding (GMAW) sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s) which heats the workpiece metal(s) causing them to fuse (melt and join) Along with the wire electrode a shielding gas feeds.
