AI Technical Summary

Technical Problem

Existing problems in pipeline welding, such as excessive weld reinforcement and uneven connection between the weld and the base material, lead to reduced fatigue life and insufficient safety of welded joints. Furthermore, existing grinding equipment is time-consuming and labor-intensive, making it impossible to efficiently complete weld grinding tasks.

Method used

A pipeline all-position weld grinding robot was designed, including a walking chassis module, a gantry truss module, an electric push rod module, a platform-type push rod module, a force control unit module, a laser sensing module, and a grinding spindle module. Through the coordinated work of these modules, the robot can achieve precise positioning and efficient grinding of the weld.

Benefits of technology

It achieves efficient grinding of pipe welds, solves the problems of excessive weld reinforcement and uneven connection between weld and base material, improves the fatigue resistance and welding quality of welded joints, and reduces the time and labor intensity of manual operation.
