1) single sided weld with double sided formation
2) one-side welding with back formation
The welding technology of one-sided welding with back formation of 16MnR steel was for vertical position welding introduced such as backing weld, multi-pass welding, cosmetic welding, and the measures emphatically how to enhance weld quality of backing weld of one-side welding with back formation were discussed.
The results indicated that the once welidng depth of penetration was 12 mm and one-side welding with back formation was realized.
3) welding by one side in shape by both sides
A particular device of location and compaction for welding by one side in shape by both sides was designed according to the enterprise s requirement in steel plates butt joint.
4) one-side welding with back
5) One Side Welding Both Sides Formation
By carrying out the EBW technology with a low current and a near-focusing manner, the inner convex of the weld is accurately controlled, the problem of external collapse is solved, and the One Side Welding Both Sides Formation technology is implemented.
6) bi-side welding molding
