AI Technical Summary
Existing stainless steel pipe straight seam welding equipment is time-consuming to align the weld seam and is prone to rotation during the welding process, resulting in low welding efficiency.
The structure employs a moving ring, an elastic block, a fixed ring, and a slider. By rotating the moving ring, the elastic block is aligned with the weld seam, and the fixed ring is used to fix the position. Combined with the retraction of the cylinder to disengage from the slider, rapid alignment and convenient welding are achieved.
It improves the efficiency and practicality of stainless steel pipe welding, and reduces the time spent aligning weld seams and the risk of rotation during the welding process.
