    Abstract

    High power diode laser (HPDL) is the newest laser type for metals processing. At this moment there are only few industrial applications in which diode laser is the most suitable laser. The most promising fields of applications for HPDL are thin steel sheet welding and hardening. The HPDL welding process is at this moment usually performed as conduction limited welding process. In this study the basic HPDL welding parameters and the effect of the parameters on the welding process, weld quality and efficiency were examined. Joint types tested were bead on plate and butt joint with different joint manufacture. The laser parameters tested were beam intensity, welding speed, incidence angle of laser beam and focal spot size. The tested parameters had an effect on the weld quality and the welding speed. The higher the beam intensity is the higher is the welding speed. The reliable welding parameters can be established for the welding of various industrial products.
