Argon arc welding is a welding technology that uses argon as a shielding gas. It has the characteristics of high current density, concentrated heat, high deposition rate, fast welding speed, and easy arc initiation, etc.

Argon arc welding is mainly used for welding of aluminum and aluminum alloys, stainless steel, copper and copper alloys, magnesium and magnesium alloys, titanium and titanium alloys, high-temperature alloys, etc.

Gas-shielded welding is a welding method that utilizes gas to protect the arc and the molten pool to achieve the joining of metal materials.
