The flow rate of flux for submerged arc welding has been investigated by using SiO2-CaO-MgO fused flux and 60° conical funnels. The circular orifice of the funnels was 4 to 12mm in diameter and the mean grain size of the flux grains was varied from 1.880 to 0.089mm. The test results indicate that the flow rate becomes almost maximum at the mean grain size range of 1.115 to 0.126mm independent of orifice diameter. An attempt to derive a new empirical equation which would represent the flow rate as a function of grain size DP and orifice diameter DO has been made. As a consequence of the study, it was possible to derive an improved equation which has better regression characteristic than other equations proposed previously.
