General information
Description | System for closed-loop control of the laser power applied to metal Laser Additive Manufacturing processes such as LMD (Laser Metal Deposition) or cladding, through the real-time monitoring and measurement of the melt-pool geometry |
Components | Infrared camera with real-time processing electronics and waterblock Connection box, multi I/O cable (3 m), power supply (24 VDC) Software package for system configuration, datalogging and log files analysis Infrared emmiter for optical calibration |
Process compatibility | Continuous LMD process (Laser Metal Deposition) Discrete cladding processes (Tracks) |
Optical compatibility | For the correct operation of the control system, it’s necessary that the optical components installed inside the laser head allow the transmission of infrared signal (above 1.1 um) from the process area to the optical port installed in the laser head. The performance of the system may be limited if lenses type BK7 are installed in the optical path. |
