Abstract
When a material to be welded is irradiated with a laser beam emitted by a processing head, a beam receiving units receive a radiated beam including a reflected beam of the laser beam and a monitoring beam that is caused by thermal radiation and is a beam having a wavelength different from that of the reflected beam. A spectrometer unit spectrally separates the reflected beam and the monitoring beam, and converts the monitoring beam into a first electric signal. A trigger unit converts the reflected beam into a second electric signal, and outputs a trigger signal when a level of the second electric signal is a predetermined threshold value or higher. When the trigger signal is input, a laser welding monitor starts, based on the first electric signal, a determination of whether or not laser welding of the material to be welded is normally performed.
