Vision guidance is used in situations where the combination of tolerance stack-ups, beam diameter, and feature size would cause inconsistent welds. The Challenge With Precision Laser Welding When you manufacture medical devices, automotive sensors, and other intricate products, failure is not an option. With tight tolerances and complicated assembly processes, consistently laser welding complex components can be a difficult task to accomplish and maintain over a long period of time in a production environment. The focused spot diameter for laser … Read More
