ABSTRACT
The article offers explanations of and corrective measures for errors that could lead to a technological and economical breakdown of the laser cutting or welding processes. Contamination due to the cutting process is one of the possibilities. The focus spot radius 1/e² should match the cutting process. The focal plane distance created by a single shot of the laser will always be different than the focal plane distance obtained by a continuous wave beam. Cutting gas and the purge gas for the laser beam path should be under constant control. Obstacales in laser welding include wrong focus spot dimensions and peak power densities, wrong or unknown focal plane positioning, cutting/shielding gas and nozzle issues, beam delivery system errors and polarization.
