Coverage of LASER WELD DEFECTS and analysis of weld defects
1. The main objective of the HDE Laser Welding Technology course is to connect the behavior of materials during welding to
the performance of the laser, beam delivery optics, tooling, weld geometry, etc.
2. Preventing weld defects (and then real time weld monitoring) is easier than correcting them afterwards! However, the
subject is ‘weld defects’ (identification of the nature and the source of the defects, how to evaluate and how to correct
them) is well covered! Look at the statics below.
3. Here are some statistics:
Total pages in the manual =

630 + hand-outs
30+% of the course is directly related to weld defects.
66 photos and illustrations related to weld defects.
20 complete sections of the manual related to weld defects.
7 computational algorithms that relate directly to weld defects.
Weld inspection methods (traditional) = several complete sections.
Weld inspection methods (real time weld monitoring) = 3 sections,
127 illustrations, 2 PPT, 1 video, and class demo of a working LWM system!
Classroom assignment: 1 – uses the supplied mathematical algorithms!
Take home the ‘code book’ on laser welding!
