Description

Technical Field

[0001] This utility model relates to the field of metal pipe welding and grinding technology, specifically to a metal pipe welding and grinding equipment. Background Technology

[0002] Steel pipes are tubular materials made of steel with a hollow cross-section. To meet usage requirements, several steel pipes are typically welded together to reach a predetermined length. After welding, a weld seam is formed on the steel pipe. The weld seam not only directly affects the quality of the steel pipe but also its appearance. Therefore, the weld seam needs to be ground. A grinding machine is a machine used to grind welded steel pipes. Steel pipes include seamless steel pipes and welded steel pipes. Seamless steel pipes are more expensive than welded steel pipes. Generally, the weld seam of steel pipes needs to be ground.

[0003] Currently, polishing is generally done manually, which is labor-intensive, inefficient, and produces poor results. Utility Model Content
