steel should be welded by high energy density welding technologies such as plasma arc welding(PAW), laser beam welding(LBM) and electron beam welding (EBW). Compared with LBW and EBW, PAW is a process with low cost and easy operation[1-3]. During PAW process, keyhole is formed inside the weld pool, and it is sensitive to any changes of the welding parameters. Whether the keyhole condition......
