AI Technical Summary
In the current metal straight seam welded pipe forming process, the misalignment between the pipe blank seam and the welding gun position leads to poor weld quality. Furthermore, improper post-weld treatment affects the welding effect and increases production costs.
Positioning cone rollers are used to position the side of the weld seam. Combined with the pre-weld positioning unit and the post-weld processing unit, including the grinding arm, grinding wheel and pre-scraping assembly, the consistency of the weld position and the surface quality are improved through the pressing and grinding of the positioning cone rollers.
This improved welding quality, reduced welding defects, ensured weld surface quality, and provided a good foundation for subsequent anti-corrosion and anti-rust treatment.
