Many systems for on-line monitoring or quality control have performed well in a laboratory environment but then failed on the production floor. Complexity, susceptibility to the environment, and cost have been the major causes of failure. LAL has developed a simple, rugged, and low-cost monitoring sensor for laser welding. A collaborative project with the automobile industry is underway to demonstrate the monitoring system's effectiveness on the factory floor. A detailed description of the weld sensor is available.
