Name:
Testing of laser welded joints using software Weld watcher
Annotation:
seams and non- destructives test with software Weld watcher. Thesis is divided into two parts, theoretical and practical. In the teoretical part is being analyzed laser, laser welding, defects of the welding seams and tests wiht Weld watcher. Thesis is focused at using laser welding in the automotive.
Practical part deals with controling settings of parametrs Weld watcher with the experiment. After reading teoretical part is the reader get to know problems laser welding and Weld watcher and he is ready to understand proces and evalution of the practical test.
Key words: Laser, laser welding, weld defects, Weld watcher Leader:
