INTRODUCTION
The High speed IR camera from NIT is a tool that helps to measure and control in real time the temperatures involved in join processes of dissimilar materials assisted by laser.
The adaptation and integration of a high-speed IR camera in a laser head as part of a flexible production line of DIMOFAC is the NIT success history.
In DIMOFAC, a high-speed IR camera was specifically adapted to the laser head of EXOM with the objective of controlling in real time the temperature of joining processes of metal and composite parts. The input coming from the IR camera was computed in real-time for closing a control loop where the power of the laser was the control parameter.
FEATURES/BENEFITS
- Real time/in line temperature measurement and control of laser based processes
- Capture and transmit information of key process parameters enabling the representation of temperature spatial and temporal distribution during the processes contributing to the creations of digital twins
- Enables fully automation of dissimilar material join processes assisted by laser
- Improves reliability and repeatability of a laser based process.

USE CASE
CLAMIR
Real time monitor and control systems for LMD and cladding processes based on high-speed IR imaging.
The system captures 1000 IR images per second of the melt pool, extract geometrical and temperature information of them and run real time close loop algorithms for modulating the power of the laser in order to keep the process stable and reliable.
