设计开发基于 DSP 的四丝脉冲 MAG 焊控制器，构建机器人四丝脉冲 MAG 焊系统，并进行了机器人四丝脉冲 MAG 焊的焊接试验，对不同相位关系下的四丝脉冲 MAG 焊熔滴过渡行为进行了高速摄影分析。试验结果表明，该四丝脉冲 MAG 焊控制器性能可靠、稳定，可实现双丝、四丝的脉冲 MAG焊接；基于四丝脉冲 MAG 焊控制器的机器人焊接系统，能够较大幅度提高焊接速度和熔敷率，提高焊接生产效率。对两种不同脉冲相位关系熔滴过渡的高速摄影图片的观察分析表明，交替和随机脉冲相位关系在多丝焊中可以较好地实现一脉一滴的熔滴过渡模式，且焊缝外观质量较好。

Based on DSP,the controller of four - wire pulsed MAG welding was designed and developed,and the robot welding system of four - wire pulsed MAG was built. The welding experiment of the system was carried out and the droplets transfer behavior of four -wire pulsed MAG at different phase relations was analyzed by dint of the high - speed photography. The results indicate that this control-ler of four - wire pulsed MAG welding was reliable and stable,which might be used in twin - wire or four - wire pulsed MAG welding;the robot welding system based on the controller might improve the welding speed and the deposition rate largely. The observation and a-nalysis on the droplets transfer photos of high - speed photography at different phase relations showed that the pulse phase relations of alternation and synchronization might facilitate the droplets transfer mode of one pulse by one droplet,and meanwhile the appearances quality of the welding seams was very well.
