摘要：
A new kind of control system for keyhole plasma arc welding(K-PAW) was developed based on the computer and the Graphics Language-LabVIEW.It can set and output the required current waveforms with desired decreasing slopes so that the corresponding "opening and closing" of keyhole can occur periodically.With this control strategy of welding current waveforms,the workpiece is fully penetrated while no burn-through occurs.Keyhole plasma arc welding experiments were conducted to verify the stability and reliability of the developed system.
