The automobile body is fabricated by welding 0.6 mm - 1.4 mm (0.024 in - 0.055 in) thick sheet steel. Spot welding is most suitable in terms of cost, quality and working efficiency. On the automobile production line, spot welding is widely used, except for some special areas which cannot use this procedure. Today, spot welding is mostly performed by robots.
In addition to spot welding MAG brazing are also used.
Soldering is not used in the automobile production line.
Automobile assembly line welding processes are shown below.
