Measurement of the Surface Tension of Liquid Metal-Droplet in Arc Welding

Abstract:

The surface tension of the liquid metal droplet was measured in the welding arc fields using a novel method. This method eliminates the interference of the electrode magnetic force and aerodynamic drag force with the measurement results during the welding process. The validity of test method was recognized by both theories and experiments. The surface tensions of the H08A wire melting droplet were measured at various currents.
