Abstract
A flux containing powder comprising titanium dioxide and suitable for use in welding to form a protective coating upon application to that side of the article opposite the side to which the electrode is applied, is characterised by the fact that in addition to the titanium dioxide in the proportion of 10-20 per cent. by weight of the powder and one or more silicates of sodium, potassium, calcium and barium in the proportion of 40-85 per cent. by weight, it contains boron oxide in the proportion of 1.5-15 per cent. by weight of the powder, the remainder of the flux consisting of methanol as a vehicle for the same. The flux may also contain borax glass, between 4 and 15 per cent. of the total flux. It is preferred to keep the content of boron compounds below 18 per cent. of the total powder. Quartz sand and fluorides may also be included in the flux powder and a suitable composition is as follows: boron oxide 8 per cent., calcium silicate 40.5 per cent., calcium fluoride 8 per cent., lithium flouride 1.5 per cent., borax glass 5 per cent., titanium dioxide 12 per cent., and quartz sand 25 per cent.
