A TIG/MIG/MAG welder is a skilled professional who specializes in various welding techniques used in metal fabrication and construction. TIG (tungsten inert gas) welding is used for high-quality welds on thin materials, while MIG (metal inert gas) and MAG (metal active gas) welding are used for faster welding on thicker materials. These welders operate welding equipment, select the appropriate welding technique, and ensure that welds meet quality standards and specifications. TIG/MIG/MAG welders play a crucial role in manufacturing and construction, creating strong and durable metal joints for a variety of applications.
