Simulated defects and associated responses from a weld sensor developed at
Argonne. | |
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.
