“…Li et al [10] showed that the heat input of high frequency pulse current was more concentrated. Kumar A. and Chen et al [11,12] analyzed the three-dimensional electromagnetic force through simulation, revealed that high-frequency current can increase arc pressure and promote molten pool flow. Qi et al [13] used the high-speed camera MS75K to capture arc of high-frequency pulse, the plasma arc with higher energy density.…”

“…At the same time, researchers have revealed the vibration behavior of the arc plasma and the flow inside the molten pool during the pulsed GTAW process, as an electromagnetic fluid dynamic system, the arc plasma and the molten pool have a fast response to changing currents [15]. As the gas flow increases, the arc cross-sectional area is compressed and the length is extended, the arc penetration capability increases with the increase of the gas flow [16].…”

The controlled short-circuit transfer is used to control the heat input of the molten pool and the base metal in the cold metal transfer welding process, including droplet formation, droplet transfer and molten pool flow. Based on the influence of arc pressure on the surface of the molten pool, droplet impact and residual energy on the flow behavior of the molten pool, this research proposes the arc pressure driving model, the droplet impact driving model and the residual energy transfer model on the molten pool surface respectively, and on this basis, a theoretical model of controlled driving and spreading of the cold metal transition bath is proposed. The theoretical relationship between the surface shape of the keyhole and the driving force, and the relationship between the surface shape of the molten pool and the welding current are established. The model accurately predicts the formation width and contact angle of the molten pool in a specific interval, which can better control the welding process and geometry.
