摘要

The method involves applying a laser beam (5) to a processing side of the cladding part (2) while applying a flow of coolant (12) to the visible side of the cladding part facing away from the laser beam. The flow of coolant is directed towards a region of the cladding part opposite a laser beam processing point.
