ABSTRACT
In the monitoring system of CO2 protection welding, based on the change of current waveform during short-circuit transition of CO2 protection welding, a trigger circuit of high-speed camera shutter is developed and designed, which can trigger the high-speed camera to take welding pool image at the right time, so as to obtain clear and non-interference photos and videos of welding pool, which has been verified in the experiment.
