Problems solved by technology

In marine engineering equipment, the welding environment of some section steel and pipelines is relatively complicated, the welding is not convenient enough, and the safety of the welding process is poor. Therefore, manual welding will continue to play an irreplaceable role, but there are still problems that need to be solved urgently
The most important issue should be the dependence of the quality of manual welding on the welder's operational skills and on-site performance. The shortage of skilled welders makes this problem more prominent

Abstract

The invention discloses an ocean engineering module structure welding method based on a VR technology. The method comprises the following steps: digital models of real workpieces are built through 3Dscanning, and corresponding 3D solid models are generated; a real welding process is caught by using a camera, and a projector is used for visual displaying on the 3D solid models; skilled welding workers finish the welding process through observing molten bath images and operating a virtual welding gun; a welding robot finishes real welding through welding parameters of the virtual welding gun; an external monitoring system transfers welding information in the robot welding process to a computer; the computer forms speed-current relation models through welding data; and primary welding workers finish welding through operating a virtual welding device according to the speed-current. The method performs virtual-real welding on ocean engineering module structures, so that profile steel and pipelines in the ocean engineering modules are welded more quickly and accurately, and the personal safety and the welding efficiency are guaranteed in the welding process.

Description

technical field [0001] The invention relates to a welding method in ocean engineering, in particular to a VR technology-based welding method for an ocean engineering module structure. Background technique [0002] As one of the important processing processes of mechanical manufacturing, welding technology is widely used in aerospace, rail transit, petrochemical, marine engineering, energy engineering and other industrial fields. Mechanized and automated welding technology can significantly improve the production efficiency, product quality reliability and consistency of mass product processing, and reduce the quality loss caused by human errors in the manual welding process. However, for complex structures or small batch product processing, manual welding still has the advantages of high flexibility and accessibility. In aerospace enterprises, certain product structures are relatively complex and cannot be mass-produced, and the processing process is still completed by manu...
