Carbon dioxide gas shielded welding, referred to as two-shielded welding, is an efficient welding technology, with its energy saving, small welding deformation, beautiful weld formation and other advantages. This welding method is especially suitable for the manufacture of stainless steel storage tanks, which can ensure the quality and use value of the storage tanks.

The equipment configuration of dioxy gas shielded welding includes welding power supply, wire feeding system, welding gun, gas supply system and control system. This welding equipment has a simple structure and is easy to operate, but the requirements for the wire hose are high, should not be too long, and the range of activity of the welding gun is relatively small.
