Reducing Risk With Vision-Guided Laser Welding

InvotecMachine Vision Systems, Micro Laser Processing, News, Precision Joining

Vision-guided laser welding is a technique that combines automated inspection with traditional laser welding to increase weld quality, improve consistency, and reduce scrap. Vision guidance is used in situations where the combination of tolerance stack-ups, beam diameter, and feature size would cause inconsistent welds. This typically occurs in manufacturing environments for medical devices, automotive sensors, and other intricate products that require flawless consistency despite tight tolerances, repetitive productions, and complicated assembly processes. Vision-guided laser welding works best in applications where … Read More
