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.
The most common types of welding include: Gas Metal Arc (GMAW). This common process, often referred to as MIG (Metal Inert Gas) welding, is carried out by automatically feeding a consumable metal electrode and shielding gas through the nozzle of a torch. In this process, the electrode is also the filler.
