Welding process for ultrathin corrugated pipe

Abstract

The invention discloses a welding process for an ultrathin corrugated pipe. The process includes the following steps that (1) proper pressure of a pressing plate is selected; (2) a pre-welding gap is adopted in the course of welding; and (3) small welding line energy is adopted. The welding process is used for welding the ultrathin corrugated pipe, burnthrough cannot happen easily and welding deformation is small.

Description

Technical field [0001] The present invention relates to a welding process, in particular, the present invention relates to a bellows welding process. Background technique [0002] The wall thickness of the corrugated pipe is generally thin, and it is easy to burn through during welding, and the welding deformation is large, especially the ultra-thin corrugated pipe is more prone to the above problems. Summary of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes an ultra-thin bellows welding process that can significantly reduce the problems of easy burn-through and large welding deformation that occur during welding. [0004] The present invention achieves the technical goals through the following technical solutions. [0005] The improvement of the ultra-thin bellows welding process is that it includes the following steps: [0006] 1) Choose an appropriate pressure plate; [0007] 2) In the welding process, use reserved gap; [0008] 3) ...
