(Laser Inline Monitor)

Measure the laser power in real time

For better quality control of laser welding.
Model : MML-200A

Laser power at every welded point and reflected laser beam can be measured, judged and saved.

▶ Features


◆ Easy quality control and data saving.

Both emitted and reflected laser beams while welding can be measured, saved and controlled. Images of samples after welded taken by a CCD camera can be monitored and saved.

◆ Judgment standard can be set based on the result data.

The upper and lower limits can be set based on the data of good weld results. Alarm is triggered when measured data is out of the set range.

◆ Brief check over the production process records.

Laser power and reflected beam intensity with the time records are displayed in a graph.

◆ Measured data can be saved in a CF card or in a PC through LAN.

Saved data are used for analysis.
