Low cost laser weld monitoring system
Laser beam welding is a joining technology that has gained increased acceptance because of its high speed, precision, and low heat effects compared to conventional arc welding methods. Argonne National Laboratory in collaboration with the automotive industry has developed a robust on-line weld monitor capable of sensing weld surface changes and penetration. The development of the weld monitor took tin account the constraints and operating environment of the factor floor in addition to monitoring needs for quality assurance. The on-line non-intrusive weld monitor developed is rugged and simple to use, does not require power to operate, is weld spatter protected and low cost; features that are desired for the factor floor. The weld monitoring technology is available for licensing. An exclusive license has been awarded to Spawr Industries for an inline weld monitor for CO{sub 2} laser applications. Licensing of the weld monitor for other implementations in CO{sub 2} and Nd:YAG laser applications are available.
