AI Technical Summary

Technical Problem

Existing technologies cannot quickly and accurately remove residual welding material from fillet welds of dissimilar steel pipe seats in thermal power plants, resulting in poor welding quality and potential safety hazards.

Method used

A method for removing fillet welds on dissimilar steel welded pipe seats in thermal power plants is provided, including cutting and separating the pipe seat, determining the bevel angle, removing the welding material layer by layer, judging the remaining welding material and treating and grinding it separately, and using polishing abrasive and etchant to ensure that the bevel meets the welding requirements.

Benefits of technology

It enables rapid and precise removal of welding material residue, ensuring that the bevel quality meets welding requirements. It is suitable for on-site operation and reduces the risk of equipment damage and personal injury.
