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.
Sometimes called MIG welding, Metal Inert Gas Welding is a form of arc welding which is great for mild steel, stainless steel and aluminum. The process involves a wire feed which goes through a wire electrode inside a welding handgun. This is the quickest form of welding because it does not require any mixing of gases.
