What is the difference between carbon dioxide welding guns and argon arc welding guns?
1. The gases used are different: the former is Ar gas, and the latter is CO2.
2. Different uses. The former can weld almost left and right welded structures, while the latter cannot be used for pressure vessels.
3. Different welding materials: the former is divided into tungsten argon arc welding and consumable argon arc welding; The latter only has a melting pole.
4. One is the welding wire used as an electrode, which is continuously melted and filled into the molten pool, and condensed to form a weld seam; Another method is to use shielding gas. With the application of consumable argon arc welding technology, shielding gas has developed from a single argon gas to a wide range of mixed gases. For example, when argon or helium is used as the shielding gas, it is called consumable inert gas arc welding (internationally referred to as MIG welding).
5. When a mixture of inert gas and oxidizing gas (O2, CO2) is used as the shielding gas, or when a mixture of CO2 gas or CO2+O2 is used as the shielding gas, it is collectively referred to as consumable active gas arc welding (internationally referred to as MAG welding).
