Zusammenfassung:	PCT No. PCT/SU81/00057 Sec. 371 Date Feb. 15, 1983 Sec. 102(e) Date Feb. 15, 1983 PCT Filed Jun. 25, 1981 PCT Pub. No. WO83/00027 PCT Pub. Date Jan. 6, 1983.A method of electroslag welding consists in mounting parts to be welded with a required gap, assembling a forming device, introducing an electrode into the gap between the parts to be welded, filling the gap with a flux, setting a slag pool with subsequent melting of the electrode and the edges to be welded, and formation of the weld. A flux for electroslag welding contains calcium fluoride, calcium oxide. According to the invention, the flux further contains calcium chloride, the ratio between calcium fluoride and calcium oxide being of 3:1.
