The welding gun combination method of industrial pipe welding equipment is generally determined according to the welded pipe material wall thickness. Generally speaking, one welding gun is used in the production of thin-walled welded pipes, which is a conventional argon arc welding gun. For thicker pipes, two welding guns or welding guns may be used to weld.

Industrial pipe welding equipment is welded with one welding gun, which is called single gun welding. Welding with two welding torches is what we call double guns welding, and welding with three torches is triple guns welding. At present, the largest number of welding guns in the field of stainless steel industrial welding pipes is to use 3 welding guns, and no more will be available, at least for now.
