Abstract: In order to study the process of laser+double wire welding, the hybrid laser + double wire MIG/MAG welding system was constructed.The method of pulsed controlling of the powers which are mutually independent is alternative.The welding experiments were also carried out with this system in this paper.The double current signals, voltage signals and high-speed camera signals were synchronously collected.The result shows that the hybrid laser+double wire MIG/MAG welding system can carry out stable welding and the appearance of the weld is good.The diversifications of voltage signals were obvious and the stability of voltage signals was improved as a result of injection of the laser power.
