Best solution for Good or bad judgment
of the laser welding and preventive maintenance.proimages/02_Laser_Markers/01_Fiber_Laser_Marker/ML-7323DL_7353DL/icon_new.jpg


MM-L400A is the weld monitoring equipment that judges all welding point in-process.
Good or bad judgment
.Workpiece gap
.Surface condition
.Focus
.Penetration

 

 Features

  • ◆ Comparison judgement

    Available for comparing good-data with bad-data. It's effective-use to judge in processing line. *Verifying in advance is needed.
    Varification
    We layered copper plates with a thickness of 1.0mm and welded them,and comppared the envelope function between a good product(no gap)
    and a defective product(with a gap).

    Result
    MM-L400A detects bad welding in reflected light and visible light.

  • ◆ Enable to detect Reflected light and Visible light(Plasma)

    Instead of the conventional model(MM-L300A) was enable to detect only Infrared radiation (Synchrotron Radiation),
    MM-L400A is enable to detect three lights of IR,Reflected and Visible(Plasma) light. Also enable to comparison test based on the preset standard waveform.

  • ◆ User friendly operating software for easy measurement
    The included MS-Viewer dedicated software enables various settings and measurements in a more intuitive manner.
    .Adjust the measurement start trigger ・Sensor sensitivity (gain)
    .Envelope setting (threshold) ・Comparison of measurement waveforms
    .I/O usage
    MS-Viewer is friendly operating software for those not accustomed to using monitoring equipment.

    On axis and outside attachment

    The light receiving unit can be equipped our focusing unit with CCD on axis and also can be set outside.
    And also, the unit can be equipped our scanner head on axis and can be set outside.

  • Supports a Scanner head

    Add an option that can be attached to our scanner head to enable monitoring on an area rather than a point.
    Easier detection of penetration during scanner welding.Please do not hesitate to contact us if you are planning to adopt MM-L400A to the third-party scanner head.

    Usage example (reference data)
    The following is data verified for perforation detection during lap seam welding of AL materials.
    Unlike the standard type (attached to the output unit), it takes a long time for the scattered metal to jump out of the measurement optical path,
    making it easy to detect as a waveform anomaly.
    Varification
    materials: AL   thickness: 1.0mm    laser power: 800W

    ◆ Light weight and Compact design

    Light weight and compact in this market. Reducing set-up space when you construct processing lines.


  • ◆ 
    High speed resolution

    Enable for high speed resolution with dedicated sensor. Monitoring not only CW laser but also pulsede laer.


  • ◆ Available for Ethernet
    It enables to monitor remotely or to manage all of data coming from each procution lines.

    ◆ Compliance with CE marking
    *some option are not available.please ask us the details.

 

 Systemup Examples

Traceability is achieved by reading the lot number,ect.,and linking the date of manufacture, processing conditions, judgment results,ect.obtained with the MM-L400A.
