摘要：This paper proposed a method on accurate phase matching control between the pulse laser and the AC TIG arc in real time, and a pulse laser-arc hybrid heat source phase matching control system is developed as well. With the utilization of this system in two typical matching cases that the pulse laser acts on the peak and the trough of the arc welding current waveform, effect regulations on weld formation, weld penetration depth and hybrid plasma shape are studied during welding on magnesium alloy AZ61. Results indicate that, when the pulse laser acting on the peak of arc welding current waveform, the weld formation is better than that of on the trough. However, when pulse laser act on the arc trough the weld penetration depth is deeper than that of on the peak. ? (2014) Trans Tech Publications, Switzerland.
