FIELD: process engineering.;SUBSTANCE: invention relates to metallurgy and may be used in slag-pot transfer car repair. Bores are drilling one crack edges and crack welding groove is performed. Crack is welded in several layers by semiautomatic welding machine at 350-500 A with welded bead joint downed relative of welding groove edges. Build-up metal is upset-forged layer by layer. Zone of fusion between welded bead joint and main metal is upset-forged to remove back side of root seam to be, then, penetrated.;EFFECT: lower labor input, higher quality.;2 cl, 1 ex
