Large-size thin-walled rocket tank cylinder segment laser welding system and method

Abstract

The application discloses a large-size thin-wall rocket tank cylinder segment laser welding system and method, and belongs to the technical field of aerospace equipment manufacturing equipment. The welding system comprises a support unit configured to provide support and adjustment platform for the workpiece to be welded; a longitudinal seam cutting and welding unit configured to position, edge cut, longitudinally gap adjust and longitudinally seam weld a plurality of workpieces to be welded; a girth seam cutting and welding unit configured to edge cut, position, girth gap adjust and girth seam weld two tank cylinder segments; and a control unit electrically connected with the support unit, the longitudinal seam cutting and welding unit and the girth seam cutting and welding unit, configured to control the running state of the support unit, the longitudinal seam cutting and welding unit and the girth seam cutting and welding unit. The application aims to solve the problems of workpiece structure deformation, misalignment, uneven gap and the like caused by the difficulty in controlling the welding seam precision in the welding process of the large-size thin-wall tank cylinder segment.
