FIELD: high temperature soldering at restoring worn cutting surfaces by applying hard-alloy abrasive composite. SUBSTANCE: soldering material includes belt-envelope, flux and solder in the form of closely arranged members. Solder is made of wire bundles in the form of cord or band and it is wrapped round at overlapping by 45 -60 degrees relative to its lengthwise axis by means of belt-envelope of polyethylene film having width 30 - 50 mm. Flux in the form of boric acid is placed in gap between belt-envelope and solder by freely pouring it. Belt-envelope is partially fused on solder. EFFECT: enhanced quality of surfaces restored by soldering. 5 dwg, 3 ex
