Process positioning device for structural welded pipe
By using a mechanical positioning component to move the welding torch along the weld seam trajectory, the problem of the welding torch deviating from the center of the weld seam during the welding process is solved, thus improving welding quality, reducing equipment costs, and adapting to complex workshop environments.

AI Technical Summary
Existing welding equipment struggles to achieve precise positioning during the welding of large pipes. Environmental factors such as light, dust, and temperature can cause the welding torch to deviate from the center of the weld, resulting in defects such as misaligned welding and edge misalignment. Furthermore, high-precision optical inspection equipment is costly and complex to maintain, making it difficult to popularize.
The mechanical positioning components, including collar, connecting rod, drive rod, guide wheel and guide, are used to move the welding torch along the weld seam trajectory, which offsets the risk of offset caused by weld seam irregularities, ensures that the welding torch is precisely aligned with the weld seam center, and avoids defects such as off-center welding and misalignment.
It achieves precise alignment between the welding torch and the weld seam in complex workshop environments, improves welding quality, reduces equipment costs and simplifies maintenance, and is suitable for small and medium-sized enterprises and complex working conditions.
