抄録

An investigation was carried out into bead formation characteristics of fused type SiO₂-MnO fluxes with various angles of electrode inclination.<BR>Ripple marks on the bead surface were very rough and clear in low SiO₂/MnO ratio, but it became indistinct with an increase in the ratio. And in case of very high ratio, the ripples was hardly able to find out. The roughness of ripples became heavy with an increase in the backward angle of the electrode, and in case of forward angle, the ripples was improved. And the improvement was more successful with flux of higher SiO₂/MnO ratio probably due mainly to increase in the slag viscosity which suppress the pool motion.<BR>The change in the ripple appearance with the electrode inclination is considered to be a function of the efficiency of the arc force acting on the molten pool. So, if the electrode is inclined forward to strengthen the arc force, the more suppressed back and forth motion caused by pulsating gas pressure in the arc cavity would result in the calm ripplse. And the fact that the electrode angle is more effective at low SiO₂/MnO ratio is considered due mainly to low slag viscocity.<BR>Besides, it was confirmed that Si and Mn content change in the weld metal hardly effect on the bead appearances.
