Abstract: The invention relates to a method for welding rotors for power generation having a plurality of rotor discs arranged along a rotor axis. The method includes providing forged and NDT tested rotor discs and machining the discs for weld seam preparation. The weld seam preparation has an inner narrow TIG welding gap and an adjoining outer SAW welding gap. The method further includes stapling the discs on top of each other; and checking the run-out of the stapled discs relative to each other and as a whole and, if necessary, adjusting the staple. In addition the method includes melting the root of the weld without weld filler using TIG welding; increasing the weld height by narrow gap TIG welding with parent metal weld filler to allow tilting of the rotor in horizontal position; tilting the rotor in horizontal position; finalizing the welding by filling the outer SAW welding gap using SAW welding; and checking the welds of the rotor by NDT using ultrasonic testing. A weld seam preparation machining step that includes preparing an optimized transition geometry of TIG welding gap to SAW welding gap transition with a first opening having a first opening angle and a second opening having a second opening angle greater than said first opening angle.

Abstract: The formation of a bellows made up of a stack of a predetermined number of ring-convolutions and having an intermediate plate supported within said stack is achieved by supplying several thin metal rings, each having inner and outer edges. A pair of these metal rings are positioned in contiguous relationship and their adjacent inside edges are welded together to form a ring-convolution. This process is repeated until a sufficient number of ring-convolutions are made to eventually make the desired bellows. Before these separate ring-convolutions are fused to each other, an intermediate plate and a support ring are made. The intermediate plate is a disc of metal that is sized smaller than the inside diameter of the rings and is secured to the support ring. The support ring is then positioned between two formed ring-convolutions in contiguous relationship and the three abutting outside edges are welded to each other to form a support plate convolution. The already made ring-convolutions and the support plate convolution are then stacked in the desired order and in contiguous relationship. All not-yet welded adjacent outside edges of said ring-convolutions and said support plate convolution are then welded to form the bellows. A bottom plate is formed and welded to the outside edge of the bottommost ring-convolution and a top ring is finally welded to the uppermost convolution to complete the bellows. The top ring is meant to be welded to a base plate of an infusion pump.

Abstract: In a method for producing a joint between a hollow profile made from steel and a component made from an aluminum material, a positive and material joint is produced by a braze welding process in conjunction with a pressing operation. The hollow profile is first pressed on a seating region of the component. Subsequently, a weld layer with an additive is applied by thermal joining, producing a positive and material joint between the hollow profile and the component. The positive joint is facilitated by first forming an end of the hollow profile to be pressed on. Preferably, forming is done by widening the end to be pressed on into the shape of a collar.

Abstract: A method of manufacturing an exhaust gas manifold, that includes metal exhaust pipes and metal flanges for attaching the pipe openings to corresponding internal combustion engine exhaust ports, employs a hybrid MIG welding process to reduce the occurrences of weld spatter being deposited on the pipe surfaces. Additional benefits are a reduction in applied energy, a resultant reduction in heat being applied to the work pieces, less consumption of weld wire, and improved efficiency of making the weld on the inside surface of the flange adjacent to the pipe opening. The hybrid MIG technique involves moving the head of the weld gun so that its weld wire tip is in contact with the closed path joint formed between an aperture in the flange and the pipe opening. Electrical energy is then applied between the weld wire and the work pieces (flange and pipe) for a relatively short period of time that is sufficient to cause the tip of the weld wire to become a molten drop. When the molten weld material is formed, the application of electrical energy is terminated and the weld wire is retracted or withdrawn away from contact to allow the molten wire drop to enter the joint and form the weld. The weld head is then moved with respect to its current location with respect to the work piece and the weld steps are repeated at a predetermined rate at each point along the joint to complete the weld between the pipe opening and the flange.

Abstract translation: 一种制造排气歧管的方法，其包括用于将管道开口附接到相应的内燃机排气口的金属排气管和金属法兰，采用混合MIG焊接方法来减少沉积在管道表面上的焊接飞溅的发生。 附加的好处是减少了施加的能量，从而减少了加在工件上的热量，减少了焊丝的消耗，并提高了在与管道开口相邻的凸缘内表面上的焊接效率。 混合MIG技术涉及移动焊枪的头部，使得其焊丝尖端与形成在凸缘中的孔和管开口之间的闭合路径接头接触。 然后在焊丝和工件（法兰和管）之间施加电能相当短的时间，这足以使焊丝顶端变成熔滴。 当形成熔融焊接材料时，终止施加电能，并且熔接线从接触回缩或撤回以允许熔融焊丝落入接头并形成焊缝。 然后，焊头相对于工件相对于其当前位置移动，并且沿着接头在每个点处以预定速率重复焊接步骤，以完成管开口和凸缘之间的焊接。

Abstract: A method of repairing a turbine rotor wheel having a damaged dovetail includes removing the damaged dovetail from the turbine wheel, leaving a turbine wheel body and welding a ring about the turbine wheel body in place of the removed damaged dovetail. During the welding process, including during preheating, welding or stress relieving, the temperature of the wheel body and ring is differentially controlled to introduce residual stresses in the ring. After welding a dovetail is formed in the ring for receiving turbine bucket dovetails. As a result, the ring has residual compressive stresses in a cold condition of the turbine whereby reduced net stresses in the ring in the location of the new dovetail during hot turbine operating conditions are reduced.
