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.
Welding is a method of permanently joining two or more metal parts. Welding involves applying heat to metal pieces which melts and fuses them, creating a strong bond upon cooling. Welders use many different welding methods for specific purposes including maintenance and repair. Given the importance of welding as an industrial process, it is not surprising that welders are employed across a broad range of industries, including construction, car racing, oil and gas, mining, and manufacturing.
