Laser Weld Monitor MM-L300A
The monitor detects welding defects and errors such as gaps between parts, missing parts, weld depth over-penetration, incorrect focus point and cover gas absence. It provides feedback to operators on the resultant laser weld quality.
It is ideal for both process development and quality control for production laser welding applications. The unit works by detecting and recording a thermal signal from the area of laser interaction and converting this into a graphical waveform.
Absolute max/min limits can be set and value envelopes can be drawn around the waveform. Once the limits are determined, the unit compares a new weld waveform in real time to identify a good or bad weld.
The compact, 3 kg (7 lb) unit reduces set-up space when integrated into a production line or used in a laboratory environment. The sensor can be mounted either on the optical axis of the laser beam trajectory or in an off-axis position.
