Welding equipment technology is generally used for the fabrication of two or more material on a permanent basis. This method is adopted in small- or large-scale industries to weld metal or thermoplastics. Various welding equipment such as gas flames, electric arcs, friction, molten metal baths, lasers, ultrasound, electron beams, and electric resistance are used globally. This fabrication process is also used to renovate and repair metal products. Welding is performed in all possible media such as in space, underwater, and air. Generally, aluminum, non-ferrous, and stainless steel are used for the fabrication of products. Nowadays, high-strength steel is widely used as automotive components along with galvanized coatings.
