After having passed the course module the student is able:
-    to compare laser materials processing processes and knows different processes special
-    identify what are the theoretical basis affecting in different processes and how they affect
the possible applications based on them
-    to know how to select and optimize proper process and processing procedure for different
-    understanding how processing parameters affect the quality of the process / part
-    to define what kind of lasers and laser systems can be applied in various processes and
applications and how they could be applied
-    is able to develop processes for different applications
-    is able to work as expert to develop laser based processes for industrial applications


Contents of this course includes e.g.:

- laser beam material interaction, transmission, reflection, absorption
- the features of different materials and laser beams affecting on phenomena
- the effect of laser based heating, melting, vaporization and ablation on material
- behavior of molten material and heat transfer mechanisms.
- formation of keyhole and phenomena connected
- knowledge on existing ways to process material with laser beam and the effect of laser
beam material interaction on that
- knowledge on most common laser processes like laser welding, laser hybrid welding,
cutting, marking, drilling, engraving, micro processing additive manufacturing and surface
treatment and the lasers and laser systems used for carrying them out
- practical cases, applications will be combined to theory
