Based on the change of current waveform during arc welding short-circuit transition process, a trigger circuit is designed to trigger the shutter of high-speed camera in arc welding monitoring system with the core of FPGA, which can solve the trigger timing problem of the camera, and obtain clear and non-interference photos and videos, which have been verified in experiments.
