Closed-loop laser power control system for Cladding, LMD and other DED techniques
Continuous monitoring of melt pool dynamics and geometry.
Ensures quality and repeatability.
Compatible with most laser heads.
Compatible with a wide range of materials.
Easy mechanical integration.
Helps to reduce CO2 emissions.
CLAMIR: LMD/DED processes
Continuous control of the laser
Avoids overheating of the part under process and allows a continuous and high quality manufacturing process.
Use of CLAMIR
Reduces rates of defective parts, material reduction cost up to 60% and saves 50% more energy than uncontrolled processes.
Constant laser power causes overheating and lack of adherence to the base material.
aser power is closed loop controlled in real time using the information extracted from the melt pool IR images.L
CLAMIR: Cladding processes
To the base material due to excess of laser power application (average reduction of dilution: > 40%)
Allows continuous processing
