Submerged arc welding process: single-sided welding of butt joints
In butt submerged arc welding, the weldment can be opened V-shaped, U-shaped or I-shaped groove, which is not only to ensure the penetration, but also to control the fusion ratio and forming. Under normal circumstances, the I-shaped groove of submerged arc welding can weld the weldment less than 20 mm at a time, and the gap needs to be left at this time.
