    WMS-100-FIO 5-in-1 Laser Welding Process Monitoring Sensor

    Process monitoring for laser welding

    WMS-100-FIO 5-in-1 laser welding process monitoring sensor is a specialized sensor engineered to detect potential defects in the laser welding process. It achieves highly efficient weld quality monitoring by passively observing spectral radiation signals and actively emitting laser light to measure melt pool disturbance, focal length shifts, and other critical parameters. With a high sampling frequency of 100MHz and 16-bit accuracy, the WMS-100-FIO 5-in-1 laser welding process monitoring sensor is compatible with red, green, and blue lasers, enabling real-time monitoring and detection of various welding defects such as incomplete fusion, spatter, pores, inclusions, burn-through, and undercut.

    Our software-defined fiber laser is based on phased-array technology, enabling a user-definable, sortable, and switchable laser spot shape with a scannable focal point. Its high power, high beam quality, and high dynamic beam shaping frequency, combined with a real-time focus correction feature, allow a single-mode laser to achieve twice the depth of focus.

    Our 5-in-1 laser welding process monitoring sensor provides real-time spatter identification. Using a high 100MHz sampling frequency, it captures sudden changes in light intensity caused by spatter. A machine learning algorithm then differentiates between normal and abnormal spatter, linking to the laser to reduce power and prevent incomplete fusion.

    Our real-time inference control platform is a highly efficient and stable system specifically developed for closed-loop laser welding control. By integrating image acquisition, spectral analysis, and real-time inference algorithms, the platform supports sub-millisecond latency from feedback to control, meeting the real-time needs for managing the intense fluctuations of the melt pool and keyhole during laser welding and additive manufacturing processes.
