The application of automated monitoring systems for laser welding enables a transparent and stable process. Process changes are recognized at earlier stages and relevant process parameters can be auto-corrected before the manufacturing process fails. Real-time process monitoring is essential for reduced scrap rate, test costs and rework.

Lessmüller Lasertechnik provides the user with smart tools, adaptable to various laser welding heads, for process tracking, understanding and optimization:

  • Reliable real-time process monitoring and quality assurance with optical coherence tomography (OCT)
  • Photodiode-based WELDCHECK system for the process monitoring of welding seams and fine points
  • Synchronous recording and evaluation of the image based data and process parameters with the WELDEYE system



Process monitoring with WELDEYE:

During the represented welding process the flux of shielding gas is measured. The marker of the Weldeye_player clearly shows the seam interruption. The pink diagram exhibits the significant decrease of the gas flux, indicating the failed weld.
