Amada Miyachi introduced its MM-L300A laser weld monitor designed to detect production errors such as gaps between parts, over-penetration, incorrect focus, and cover gas absence.
This compact high-resolution laser weld monitor determines weld success by detecting and recording a thermal signal from the area of laser interaction and provides an output waveform around which limits (max/min or envelope) can be set.
Once the limits are set, the unit compares a new weld waveform in real time to identify good or bad weld.
The MM-L300A delivers high temporal resolution down to 1 microsecond. The SU-N300A dedicated thermal sensor enables precision monitoring of both CW and pulsed lasers.
It also features easy-to-use software for simple sensor configuration, waveform envelope limit set-up, and real-time or saved waveform analysis on Windows® PCs.
With machine-selectable setup schedules, the unit can monitor different welding conditions. The unit, weighing only 7 lb (3 kg), reduces set-up space when integrated into a production line, and the sensor mounts either on the optical axis of the laser or in an off-axis position.
