Abstract: The quality of a weld depends, to a large extent, on the filler material and type of welding.Welds and surfacing welds were produced with submerged-arc welding.The welding current was varied.The flux with a fineness of 0.2-1.8mm was used.During the welding process, the welding flux melted and the liquid slag was formed.After the input of heat was stopped, the solidification of the slag began and different mineral phases started to precipitate.We found out that besides the basic constituents listed by the manufacturer of the welding flux, the alloying elements and deoxidizers from the flux and from the melt are also present in the slag.Based on these results, it can be concluded that in the case of reusing the welding slag for the production of welding flux, it is important to consider the composition of the welding slag.Keywords: submerged-arc welding,
