A welding machine is a device used to join two or more metal parts by heating them to their melting point and fusing them together. It typically works by generating an electric arc, which produces the heat necessary for melting the base materials, and may also involve a filler material to create a stronger bond. Welding machines come in various types, such as MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), and stick welders, each suited for specific applications and materials. These machines are essential in industries like construction, automotive, shipbuilding, and manufacturing, providing strong and durable metal joints for structural integrity and functionality
