AbstractThe CO2 arc welding was carried out under a longitudinal magnetic field, and the arc shape has been studied by using a high-speed camera. From 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 expand. It would become a bell-type shape and rotate at a highspeed in the optimum range of magnetic field parameters. The 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 CO2 welding arcs.
