ABSTRACT:
A ceramic flux for welding low-alloy steels contains calcined magnesite, synthetic slag containing two thirds of CaF.sub.2 and one third of Al.sub.2 O.sub.3, a component containing at least 95% of Al.sub.2 O.sub.3 in the alpha form, wollastonite, marble, barium fluoride, ferrotitanium, ferroboron, sodium silicate.
The ratio of the total content of calcined magnesite, two thirds of synthetic slag and one half of wollastonite to the total content of the component containing at least 95% of Al.sub.2 O.sub.3 in the alpha form, one third of synthetic slag, one half of woolastonite and two thirds of sodium silicate ranging from 1.30 to 1.43 and the ratio of titanium to boron ranging from 11.2 to 30.1.
