Process Monitoring and Control of Laser Beam Welding

Abstract

Laser materials processing is widely used in industry today. For a long time, the statement „the best sensor is no sensor”︁was mentioned often in this field of technology. However, a change of paradigm can now be observed. ISO 9000 and other by law‐enforced regulations have led to the understanding that quality control is an essential tool in modern manufacturing and necessary in order to keep production results in deterministic boundaries.
