Types of laser welding monitoring systems

Laser welding monitoring systems are mainly divided into the following types:

Visual monitoring system: Use cameras and image processing technology to monitor the welding process in real time and identify welding defects and undesirable phenomena.

Acoustic monitoring system: By analyzing the acoustic signals generated during the welding process, welding defects can be quickly identified, such as uneven welds, cracks, etc.

Optical monitoring system: Using laser scattering and reflection phenomenon, you can monitor the temperature distribution of the welding area and the state of the weld pool to ensure the quality of the welding.

Electrical signal monitoring system: by monitoring the welding current and voltage, you can find the abnormal situation in the welding process in time, such as arc instability.
