AI Technical Summary

Technical Problem

The welding process of existing medium and thick plates is cumbersome, the material consumption is large, the production efficiency is low, and welding defects are easy to occur, affecting the quality of the weld.

Method used

The reverse deformation welding tooling of the medium and thick plate single-face butt welding of horse-free plates is adopted, including a magnetic reverse deformation platform and a hoisting device. The binding force and reverse deformation angle are provided through the electromagnet to realize horse-free plate assembly and single-sided submerged arc welding.

Benefits of technology

The assembly of medium and thick plates without horses has been realized, which improves welding efficiency and quality, reduces material consumption and production costs, and does not occupy driving and lifting resources, and optimizes resource allocation.
