Laser welding method, device and equipment and storage medium

The invention discloses a laser welding method, device and equipment and a storage medium, and belongs to the technical field of laser welding. The method comprises the following steps: acquiring synchronously output triangular waveform data and control waveform data; wherein the control waveform data comprises periodically output trigger waveform data, and on a time axis, peak segments or trough segments of the trigger waveform data and the triangular waveform data correspond to each other; and when the control square wave data is the trigger waveform data, the laser is controlled to stop outputting laser. Starting and stopping of welding are controlled through the control waveform data synchronously output with the triangular waveform data on the time axis, and when the control waveform data comprise the periodically-output trigger waveform data corresponding to the wave crest section and the wave trough section, the output trigger waveform data control the laser to stop outputting the laser. Therefore, the
