CLAMIR. Closed-loop laser power control system for Cladding and Laser Metal Deposition processes
CLAMIR is a process control system for Laser Additive Manufacturing that measures and maintains the melt pool geometry through a closed-loop control of the laser power using a 1,000 image per second MWIR camera
Accurate process control
Closed loop control of the laser power unit at high-speed
MWIR imaging monitoring
On-axis process observation with a high-speed uncooled MWIR camera (1000 images per second)
Compatibility with LAM processes
Laser Metal Deposition (LMD), laser cladding
Easy mechanical integration
The system is attached to an optical port of the laser head
Higher dynamic range
Monitoring of temperatures starting at 100 ºC
Analog output
Compatible with Laser Power Units controlled with analog output (0V – 10 V)
Overall, PbSe sensor technology enables strong improvements in the accuracy and reliability of monitoring and closed-loop control of laser processing, compared to systems based on CMOS
