What's the difference between double-sided shielded welding and manual arc welding?

1, the difference is not big, CO2 welding should be easy to use. Manual welding pays more attention to the observation of molten pool and the change of covered electrode angle.

2. Manual arc welding uses various methods to protect the welding pool from contact with the atmosphere. Thermal energy is provided by electric arc. Like MIG welding, covered electrode is consumable. The metal electrode is coated with mineral flux, and when the flux melts, welding slag (coating) is formed to cover the welding pool. The coated flux releases gas to protect the welding pool and contains alloying elements to compensate the alloy loss of the alloy pool.

3. 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.
