Carbon dioxide gas shielded welding is a kind of welding method, which uses carbon dioxide gas as shielding gas for welding. Simple operation in application, suitable for automatic welding and full welding. Welding should be windless and suitable for indoor operation.

Welding current mainly depends on wire feeding speed. The faster the wire feeding speed, the greater the welding current. Welding current has the greatest influence on weld penetration. When the welding current is 60~250A, that is, when welding in the form of short circuit transition, the weld penetration is generally1mm ~ 2 mm; Only above 300A, the penetration depth increases obviously.

Extended data:

Due to the special influence of the thermophysical properties of carbon dioxide gas, it is impossible to form the axial free transition of metal liquid balance at the end of welding wire when using conventional welding power supply, and short circuit and droplet necking explosion are usually needed. Therefore, compared with the free transition of MIG welding, the splash is more.

However, if a high-quality welder is used and the parameters are properly selected, a very stable welding process can be obtained and splashing can be minimized.

Because the shielding gas used is cheap, the weld seam is well formed when short-circuit transition is adopted, and high-quality welded joints without internal defects can be obtained by using welding wire containing deoxidizer.

Therefore, this welding method has become one of the most important welding methods for ferrous materials.
