✦ Synopsis

Although transmission laser welding is highly reliable and characterized by high levels of process parameter repeatability, unforeseen influences can give rise to unsatisfactory welding results in practice. Therefore an early on detecting of defective welding has to be warranted to avoid defects in the weld seam. Unlike most of the other conventional monitoring methods used with transmission laser welding, the reflection diagnosis technique involves the direct analysis of the welding seam. In addition to measuring the height of welded components, it can also be used to detect a wide range of faults, and therefore ensure the quality of the seam.
