Abstract
PURPOSE: To improve welding workability, by specifying the compositin of flux in using anhydrous potash glass powder as potassium source.
CONSTITUTION: Anhydrous potash glass powder containing, by wt., ≤10W35% K2O, 3W30% CaO, and 35W85% SiO2 is added to the flux by 0.5W15wt% of the total weight of flux. Moreover, the flux is controlled so that it may contain 5W35% SiO2, ≤20% CaO, and ≤10% K2O. In this case, if the potash glass is not anhydrous one, the arc will be disturbed. The anhydrous potash glass is low in melting point, promotes the melting of other raw materials, and facilitates the mixing of objective elements. Moreover, the stability of arc can be maintained because of the low-moisture absorbing property of the glass. The lower and upper limits of K2O are required for the workability and generation of bead dropping, respectively. The lower and upper limits of CaO are required for improvement in the moisture absorbing property, and improvement in the melting temperature and generation of undercut, respectively. The lower and upper limits of SiO2 are required for the moisture absorbing property, and generation of undercut, respectively. Moreover, the lower and upper limits of adding amount of glass mentioned above, are required for the workability and exfoliation of slug and the shape of bead, respectively. In addition to the above, limitation of each element contained in the flux is required for the workability.
