摘要

Abstract: In laser cutting and welding processes time-unsteady phenomena dominate the fluid phases generated by high power laser interactions with workpiece material and assist gases. Violent reactive mixed fluid-flows with phase transitions must be understood and controlled to significantly improve current processing. An extensive experimental and phenomelogical analysis has shed some light on the events taking place and clarified some of the most puzzling aspects of the problems. New nozzle designs for the welding and cutting processes are proposed and have been proven promising in preliminary testing.!18
