AI Technical Summary

Technical Problem

Existing flange welding equipment cannot make the centers of two flanges coincide, and cannot guarantee the clamping and fixing of pipes of different specifications, especially when welding on pipes that are broken in the middle.

Method used

An auxiliary tooling was designed, which includes a clamping mechanism and a moving component. The clamping mechanism ensures that the axes of the two pipes are aligned, and a laser marker is used to make the flange bolt holes aligned. The moving component provides driving force to bring the flange closer together to complete the welding.

Benefits of technology

This enables axial alignment of pipes of different sizes, ensures consistent flange bolt hole centers, facilitates valve bolting, and improves welding accuracy and stability.
