A novel seam extraction method based on nearest point for non-groove butt weld seam

Abstract

The weld seam extraction algorithm is the core of the automatic welding method for robots guided by vision, which has been widely studied. As a common type of welding model, butt weld without groove also has many weld seam extraction algorithms. However, these algorithms mainly rely on the shape of the workpiece or the seam, which results in limited applicability. To improve the adaptability of weld seam extraction algorithms, this paper focuses on the characteristics of non-groove butt joint weld and proposes a weld seam extraction algorithm based on nearest point and registration. Experimental results have shown that this method has high versatility and practical value.
