Therefore, it is widely used. Submerged arc welding includes processes such as depositing flux, igniting the arc, continuously feeding wire, moving the arc along the welding direction and finishing the welding.

[0003] Submerged arc welding requires the use of a flux depositing mechanism in advance to evenly deposit the flux on the assembled workpiece welding point, and then use a wire feeding mechanism to continuously and stably feed the welding wire into the welding arc zone for continuous welding.
