Abstract: A method for sizing a section of a junction by orbital friction welding with an eccentric e, between a blade and a stub of a bladed disk for a turbomachine. The sized section has a rounded contour at one or two ends of said section along a chord of the blades, each corresponding to a leading edge or a trailing edge of said blades, said rounded contour(s) having over a sector of at least 120° an average radius of at least twice the eccentric e.

Abstract: A process for orbital friction welding of a blade to a stub on a turbomachine rotor disk, comprising the following successive phases: friction of the blade against the stub with application of a force friction normal; forging of the blade against the stub with application of a normal forging force; wherein the normal forging force is greater than the normal friction force and essentially constant throughout the forging phase.

Abstract: A method for sizing a junction section by orbital friction welding between a blade and a stub of a bladed disk for a turbomachine. The section is sized such that the ratio of an average ray length extending fully into the section from a point at the periphery of said section and sweeping across said section, where said average ray length is a maximum average length, and an average length of rays extending completely into the section from another point at the periphery of said section and sweeping through said section, where said average length is a minimum average length, is less than or equal to 2.

Abstract: A welded structural assembly and method, in one form, includes an upper substrate, a lower substrate adjacent the upper substrate, a fastener, and a sealing member. The fastener includes a shank portion, a first head portion, and a second head portion. The shank portion extends through the upper substrate and into the lower substrate. The shank is welded to the lower substrate. The first head portion has an outer periphery and an underside. The second head portion is frangibly coupled to the first head portion. The sealing member is disposed under the first head portion between the upper substrate and the first head portion. The sealing member contacts the underside and extends beyond the outer periphery such that the sealing member extends radially outward beyond all points of the first head portion.

Abstract: A method and apparatus for joining using friction and current, wherein the friction/current joining apparatus includes a friction device, a forging device, an electrical current source, and a programmable controller, as well as workpiece holders for the workpieces to be joined. The friction/current joining apparatus is controlled such that, in a contacting phase, the workpieces are initially moved along a process axis, and their mutually facing joining surfaces oriented transverse to a common process axis are brought into contact. In a grinding phase, while subjected to contact pressure by mutual relative movement, the joining surfaces, are ground together and made smooth. At the end of the grinding phase, the relative frictional movement is permanently stopped and, in a forging phase following the grinding phase, the workpieces are pressed together, plasticized, and joined while subjected to contact pressure on their contacting joining surfaces along the process axis, and subjected to conductive heating with electrical current.

Abstract: A flowing direction of a cooling liquid introduced into a heat sink is a direction perpendicular to a stacking direction. Each of the plates has a plurality of holes. In a state in which the plates are stacked in the stacking direction, flow paths formed by the holes of the plates being connected to each other in the stacking direction and the flowing direction have helical shapes toward the flowing direction. Helix center axes at helix centers of the flow paths are formed in only one row in the stacking direction.

Abstract: In performing friction element welding of a sheet set constituted by two or more metal sheets, an element is press penetrated into the sheet set. The element may include a round columnar mandrel; a disc-shaped collar provided at an upper end face of the mandrel; and a conical pin extending from a lower end face of the mandrel. The element has a plurality of fluidized-metal discharge grooves arranged spirally in a flat area of the lower end face of the mandrel, the flat area excluding the pin. Alternatively, the element may include a round columnar mandrel having a lower end face that forms a conical face with an apical angle αm, the conical face having one or more pairs of chippings discharge grooves or having a plurality of cutting edges, the chippings discharge grooves each extending in a curved manner from an apex of the conical face.

Abstract: The present disclosure concerns an extrusion profile extending comprising: parallel and spaced-apart upper and lower panel members; and an inner core between the upper and lower panel members, the inner core being integral with and connecting the upper and lower panel members, the inner core comprising first and second curved connecting members having a concave side and the concave sides defining first and second concavities opened outwardly, each of the connecting members merging smoothly with each of the panel members in upper and lower panel-connecting portions of the inner core, the panel-connecting portions being offset inwardly with respect to the panel members to define assembling clearances in marginal edge regions of the upper and lower panel members. It also concerns a method for assembling a panel structure comprising a plurality of extrusion profiles and a corresponding modular structural assembly.
