Problems solved by technology

However, the use of manual argon arc welding has the disadvantages of many bottoming times, large deformation and low efficiency, while the method of electron beam welding seam splicing needs to divide the original weld seam into at least 8 pieces for tailor welding, so there are many problems in the welding process. Problems such as flipping parts out of the box for the first time, many times of vacuuming, many overlapping areas, and discontinuous welding quality

Abstract

The invention relates to the technical field of metal material welding, and discloses a method for continuously welding an irregular revolved body workpiece through an electron beam. The method can greatly improve the welding quality and the welding efficiency and realize the vacuum electron beam rapid welding of an irregular revolved body, and meanwhile, a practical and effective weld joint solution is provided for welding of parts similar to cam structures.

Description

technical field [0001] The present application relates to the technical field of metal material welding, and in particular to a method for continuously welding irregular rotating workpieces with electron beams. Background technique [0002] Since most of the electron beam welding equipment is fixed grab type, it is necessary to realize the welding of the workpiece through the movement of the worktable during the welding process. For regular rotary workpieces, the smooth welding of workpieces can be achieved through the uniform rotation of the workpieces, while for irregular rotary workpieces, such as the attachment figure 1 The parts shown are usually multi-pass welded by manual argon arc welding or joined by electron beam welds. However, the use of manual argon arc welding has the disadvantages of many times of backing, large deformation and low efficiency, while the method of electron beam welding seam splicing needs to divide the original weld seam into at least 8 pieces...
