Abstract: A method for manufacturing a rotor by welding a plurality of elements together is described. The elements have a body with cavities and surfaces to be welded to surfaces of adjacent elements. According to the method, the elements are vertically stacked one above the other to form a pile with facing surfaces to be welded together defining slots. The cavities of adjacent elements define bores that extend within the pile. Then, adjacent elements are welded together within the slots. The bore is purged with an inert gas or mixture during welding. The slots are welded at an upper part of the bore before the slots at a lower part of the bore, and a slot at the upper part of the bore is welded last.

Abstract: In a method for joining two, in particular rotationally symmetrical, metal parts (1, 2) by a tungsten inert gas (TIG) welding process, in a first step, the two metal parts (1, 2) to be joined are initially positioned relative to one another by a centering offset (7) in such a way that a narrow gap (4) is formed between them and a relief region (8) is created in the seam-bottom area. In a second step, the flanks (5, 6) of the metal parts (1, 2), which delimit the narrow gap (4), are joined together by welding beads (10) which fill the narrow gap (4), with a predetermined melt-through point (9) being formed. High-quality automatic welding is achieved in that the narrow gap (4) has a continuously constant width (a), in that the width (a) of the narrow gap (4) is selected such that the welding beads (10) lying one above the other each extend over the entire width (a) of the narrow gap (4), and in that the entire narrow gap (4) is filled with the welding beads (10) in fully automatic fashion.

Abstract: A method for producing a welded rotor of a low-pressure steam turbine, the method including providing a first forging including a steel with a minimum yield strength of approximately 700 Mpa. A second forging is provided including a heat-treated 3.5 NiCrMoV stel having an average chemical composition of 3.5% of Ni, 1.5% of Cr, 0.35% of Mo, 0.10% of V, 0.25% of C, remainder Fe. A build-up layer of welding deposit is applied to a connection surface of the second forging using build-up welding. A first local post-weld stress-relief annealing is performed so as to soften the build-up layer and a corresponding heat-affected zone. The first and second forgings are joined together so as to provide a welding location. The welding location is filled using a welding deposit so as to provided a welded join. The welded join is subjected to a second post-weld stress-relief anneal.

Abstract: In a method for welding together two parts (12, 13), especially of a turbomachine, which are exposed to different temperatures, of which the first part (12) consists of a steel and the second part (13) consists of a nickel-base alloy which contains elements which are unfavorable for welding to steel, such as for example Nb, a crack-free welded joint is achieved by the fact that first of all an intermediate layer (18), in which the amount of unfavorable elements is progressively reduced from the inside outward, is applied to the joining surface (17) which is provided for the welding, and that then the second part (13), which has been provided with the intermediate layer (18), is welded to the first part (12).
