3. City welding method;
4. Steel fixation method;
5. Hammer striking weld seam method;
The boundary deformation can also be controlled by adjusting the welding sequence.
Attachment:
Anti deformation method:
During welding assembly, the workpiece is artificially deformed in the opposite direction of the welding deformation in advance.
