Description

(1) Technical field [0001] The invention relates to a multi-welding power source group control system (2) Background technology [0002] Driven by microelectronics and digital technology, some digital intelligent welding power sources have appeared. When the external parameters fluctuate, they can rely on the control system of the welding power source for self-adjustment to achieve the stability of welding parameters, thereby ensuring welding quality. At present, there are intelligent welding power sources such as EWM's lintegrai series and Fronius' Transplus synergic series, which are the results of digitalization; there are also control algorithms for welding power waveform control, estimation and modeling of welding power internal characteristics, and comprehensive performance control for GMAW welding. , these control strategies have achieved positive results in reducing the impact of external voltage fluctuations on the welding process of a single welding power source. ...
