Abstract
The composition of a new general-purpose ceramic flux for welding of carbon steels is described. The flux is not susceptible to hydration, has low chemical activity in relation to deposited metal ensuring minimum oxidation of the alloying elements, with easy separation of the slag layer immediately after welding. Consequently, no labour-consuming operations are required for the removal of the slag from the surface of the welded joint. The flux ensures efficient melting with the edges of the welded components and prevents the formation of unacceptable defects in the weld metal.
