AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.
