Intelligent Guidance Programming of Welding Robot for 3D Curved Welding Seam

Abstract: Due to the limitations of welding complexity and machining error, traditional manual teaching and offline programming are not intelligent enough and have weak adaptability to workpiece. At present, the 2D perception visual welding guidance programming method is commonly used which cannot accurately locate and model the complicated 3D spatial curve welding seam. The 2D perception method can hardly meet the requirements of welding process. In this paper, a welding seam perception method based on a line structure… Show more

“…In recent years, the use of robots in industrial manufacturing has significantly increased. Among the different industrial robots, welding robot plays a crucial role in reducing the cost of manual welding and improving the stability of welding quality [1,2]. However, the existing welding robots operate on a 'teach-and-playback' mechanism [3,4], which limits their capability to adapt to the welding process, especially the medium-thick plate welding.…”

“…For example, Zhou et al [4] proposed a welding seam sensing method based on a line-structured light sensor and constructed an intelligent guidance system for a welding robot. Li et al [5] designed a dual-station intelligent welding strategy based on charge-coupled device (CCD) visual detection system.…”
