The SPAWR Laser Process Monitor was developed through a CRADA program between Argonne National Labratory and SPAWR Industries, Inc. In 1998 the Process Monitor received the Federal Laboratory Consortium's Award For Excellence in Technology Transfer. Over 30 units are currently in operation throughout the world.

Patent #5,674,415 (and others pending) is a non-intrusive device capable of real-time remote sensing of process penetration, depth and quality. The monitor serves as an in-line, real-time quality control system. It is one of the most important quality control technologies since the use of automated laser welding.
