We used a camera for the inspection of defects during tailored welding, such as pits (holes), meandering, and undercut. Since the detection sometimes failed by the color variation of welding, we adopted the LJ-V Series 2D Laser Displacement Sensor. The detection is not affected by color variation and we were able to improve work efficiency.
Thank you for using KEYENCE products. The appearance inspection with the LJ-V Series 2D Laser Displacement Sensor judges defective welding based on the shape so that the detection is not affected by color variation. Since the LJ-V Series is a displacement sensor, its ability to perform bead height inspection has also satisfied customers.
