Abstract

The inspection of weld seam is important for high quality of welding. This paper deals with the issue of visual measurement and inspection of weld bead and defect detection in tailored blanks laser welding. A visual inspection system based on laser structured light and gray image has been developed for weld bead profile monitoring, measuring and defect detection. Image processing and extraction algorithms of the laser profiles and feature points are presented. Experiment was conducted with the visual inspection system using structured light and gray image and experimental results validate the effectiveness of the method.
