Novel penetration close-loop control system for keyhole plasma arc welding

SUN Jiu-wen,CHEN Qiang,SUN Zhen-guo,WANG Yao-wen(Department of Mechanic Engineering,Tsinghua University,Beijing100084,China)  
A penetration close-loopcontrol system which taking welding current and plasma gas flow control as adjusting variables,has been established.Wavelet method has been used to detect penetration from arc welding voltage correctly in real-time.Through the sync control of welding current and plasma gas flow,the one-keyhole-per-pulse welding process has been realized successfully.Experimental results show that the system has increased penetrating force of plasma arc apparently and keyhole plasma arc welding has been successful in welding stainless steel with10mm thick.Moreover,the system possesses good response property,the disturbances from gradual change and break change from3mm to6mm thick have been come over,therefore the continuous stable and reliable keyhole plasma arc welding could be fulfilled in thicker steels.
