A digital synchronic control system for twin-arc high-speed SAM was presented by IPC(industrial personal computer) and PLC.By adopting the way of software programming, the functions of parameters optimization settings, digital control for the timing of twin arc-starting and arc-ending were achieved, which was to achieve precise control of arc energy parameters and to guarantee stability of synchronic control among the arcs. The design of hardware and software of the digital synchronic control system was also discussed. The results of weld experiments demonstrate that the developed digital synchronic control system meets the design requirements. The process of the twin-arc high speed SAW are stable, perfect forming of weld seam, which achieves technology of twin-arc high-speed SAW.
