(2) Welding deformation is effectively prevented and alleviated.
(3) The workpiece is in the best welding position, the weld formability is good, the process defects are obviously reduced, and the welding speed is improved.
(4) Mechanical devices are used to replace the heavy work such as positioning, clamping and workpiece turning when assembling parts by hand, which improves the working conditions of workers.
(5) It can expand the application range of advanced process methods and promote the all-round development of mechanization and automation of welding structure production.
