主　　题：longitudinal magnetic field high speed camera the arc of CO_2 welding computer simulation technology 

摘      要：The COarc welding was carried out under a longitudinal magnetic field,and the arc shape has been studied by using a high-speed *** the camera images,we know that under the action of the longitudinal magnetic field,the upper end of the arc will constrict and the lower end of the arc will *** would become a bell-type shape and rotate at a highspeed in the optimum range of magnetic field *** arc shape was simulated using a mathematical model,which was established based on experiment data and theoretical knowledge,and mechanism analysis has been carried out regarding the effect of longitudinal magnetic field on COwelding arcs.
