Paper Abstract

Applications of high power lasers in material processing can be divided into surface treatment, welding and cutting. An overview of the main physical mechanisms underlying these applications shall give a systematic basis for modeling the processes. The absorption behavior of a CO2-laser beam is discussed, mathematical attempts for describing the heat conduction are compared and a distinction between the several appearing melt flow phenomena is made. Further treated effects are evaporation, plasma formation and time dependence. Models of hardening, deep welding and cutting are presented to give examples for the mathematical treatment and the predictions and analysis that can be done.
