Monitoring of remote laser processes using air-coupled ultrasound
Authors: Contents:- XARION’s optical microphone was used for contact-free monitoring of laser processes by comparing the acoustic emissions of the process to known reference signals
- In this paper, this monitoring method was shown to be able to detect defects and irregularities in the welding of metal sheets and of direct copper bonded substrates
