On-Line Visual Inspection System for Backside Weld of Tailored Blanks Laser Welding

摘要：

In tailored blanks laser welding,the quality of backside weld has a significant influence on mechanical properties of weldment This paper deals with the issue of visual measurement,inspection of weld bead and defect detection in tailored blanks laser welding.An inspection system based on laser structured light vision has been established for backside weld bead measuring and defect detection.Image processing and extraction algorithms of structured light profiles and feature points are presented.Dimensional parameters are measured and weld defects are detected in the process of tailored blanks laser welding.The experiment results demonstrate that the proposed inspection system and method are suitable for backside weld quality inspection of tailored blanks laser welding.
