Zusammenfassung:	Work pieces to be joined together by the flash butt welding method are brought together at a preset no-load voltage, the end faces of the work pieces are fused, and an upsetting is accomplished. The amount of the upsetting is determined within from 1.2 to 3.0 of the amount of the maximum gap between the end faces of the work pieces being welded together, which gap forms in the course of fusing the end faces of the work pieces. The maximum gap is determined from the following relation: DELTA max=f(Uo, delta ), where: DELTA max=maximum gap; Uo=no-load voltage; delta =thickness of the work pieces being welded together. Empirical formulas to determine the maximum gap for work pieces of various thicknesses are presented.
