Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.as tungsten arc welding (GTAW), or tungsten inert gas (TIG) welding, is a manual welding process that uses a nonconsumable tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material.
MIG and TIG Welding. GMAW, commonly known as MIG welding, is an arc welding process which produces the coalescence of metals by heating them with an arc between a continuously fed filler metal electrode and the work.IG and TIG Welding.
