Process monitoring at laser welding of Thermoplastics

  • A pyrometer, integrated into a 3D‐scanner, offers the possibility to measure the weld seam temperature at quasi‐simultaneous laser transmission welding. Experimental studies have shown that gaps located in the joining zone can be identified by a temperature rise even at a high scanning velocity. This enables the implementation of algorithms for observation and control strategies.
