Arc Characteristics and Metal Transfer for Flux-Cored Electrode in GMA Welding (Report II)(Welding Physics, Processes & Instruments)
Search this Article
Arc characteristics and metal transfer with flux-cored wires which have various content ratios of iron powder in flux were studied. The increase in adding ratio of iron powder into flux in flux-cored wires diminished their melting rate of wire and the size of transfering droplets. Moreover the distribution of size of droplets was measured. The size of droplets transfered with flux-cored electrode in free-flight transfer mode was similar to that with solid wire in spray transfer mode. The effect of the compositional ratio of CO_2-Ar shielding gas on the size of droplets transfered was a little with flux-cored electrode.
