Abstract

Laser offers unique capabilities for high energy concentrations at small surfaces. Factors that have influences over interactions between laser beam and steel surfaces have very high control. Pulse laser YAG:Nd is usually used for cutting and welding. Paper is based on hardening experiments using KVANT 17 (YAG:Nd) pulse laser over 38MoCrAl09 steel. Results were investigated by hardness (HV5) macrographic and micrographic method.
