Abstract:
The present application relates to a process for connecting two aircraft fuselage segments (10a, 10b) and a reinforcing profile (14) arranged in the joint region (11) of the two aircraft fuselage segments (10a, 10b) by friction stir welding using a rotating tool (18), where in that a cover plate (20) is brought onto the aircraft fuselage segments (10a, 10b) to be connected above the joint regions (11) and after the friction stir welding the remainder of the cover plate (20) is milled off. This makes it possible to overcome significantly greater gap tolerances in the edges to be connected so that the dimension tolerance requirements for the aircraft fuselage segments (10a, 10b) can be reduced. Furthermore, a smooth surface can be achieved in the welding region.
Abstract:
Un élément de structure comprenant au moins deux parties en alliage d'aluminium présentant différents compromis de propriété, lesdites au moins deux parties étant soudées et dans lequel l'une desdites parties est (i) choisie dans un alliage d'aluminium différent de l'autre desdites au moins deux parties et/ou est (ii) choisie dans d'un état métallurgique initial différent de l'autre desdites au moins deux parties, et dans lequel au moins une desdites au moins deux parties a été pré-revenue avant d'être soudée, et dans lequel ledit élément de structure a subi un revenu post-soudage conférant un état métallurgique final à chacune desdites au moins deux parties. Les parties sont avantageusement soudées par soudage par friction-agitation. Un autre sujet de l'invention est un procédé de fabrication dudit élément de structure.
Abstract:
A composite aluminium panel comprising two parallel plates and/or sheets secured to the peaks and troughs of a corrugated aluminium stiffener sheet between the parallel plates and/or sheets, wherein the corrugated aluminium stiffener sheet is made from an aluminium alloy rolled sheet of composition (in weight percent): Mg 1.5-6.0, Mn 0.3-1.4, Zn 0.4-5.0, Fe up to 0.5, Si up to 0.5, Zr up to 0.30, optionally, one or more of (Cr 0.05-0.30, Ti 0.01-0.20, V 0.05-0.25, Ag 0.05-0.40, Cu up to 0.40), others up to 0.05 each, 0.15 total, Al balance, and having in an H-condition or in the O-condition a ratio of PS/UTS in the range of 0.4 to 0.9 and having good roll formability.
Abstract:
The invention relates to a method for producing a component (1) from a plurality of profiles sections (2) by means of welding, said profiled sections (2) having an at least partly different design. According to the invention, the profiled sections (2) are to be fed to a conveyor (3) in a presorted manner and then centered and combined before being connected along a joint line (10) by laser welding and transported away.
Abstract:
A method of manufacturing a container is disclosed which comprises positioning metals plates (12, 14) against one another to define an interior space and welding the seams between the plates (12, 14) to form a fluid tight container. In the invention, the interior space is filled with a granular refractory material (30) prior to the welding of the seams, in order to prevent any weld spatter from adhering to the interior of the container and/or to prevent burr from being created at the seams.
Abstract:
The present application relates to a friction stir welding tool (20) for joining two adjacent work pieces (10), which work pieces comprise portions (6) to be welded and having a narrow space there between on one side, said tool having an axis of rotation, and comprising a first shoulder (1), a second shoulder (2), and a pin (3) arranged so as to connect the first and second shoulders, wherein said first shoulder has a first contact surface for friction heat generation to the work pieces to be joined during welding, said first contact surface having a first contact area, and said second shoulder has a second contact surface for friction heat generation to an opposite surface (5) of the same portions of the work pieces to be joined, said second contact surface having a second contact area, the first and second areas having different sizes, where the first area is a larger sized area than the second area. The application also relates to a method of joining work pieces, a product comprising joined pieces, and the use of such friction stir welding tool.
Abstract:
A friction stir welding tool for joining two abutting work pieces is described, wherein said tool has an axis of rotation (R), and comprises a first shoulder (1), a second shoulder (2), and a pin (3) arranged so as to connect the first and second shoulders, wherein said first shoulder (1) has a first contact surface, which is to be in contact with one surface (4) of the work pieces to be joined during welding, said first contact surface having a first area essentially perpendicular to the axis of rotation, and said second shoulder (2) has a second contact surface, which is to be in contact with an opposite surface of the work pieces to be joined, said second contact surface having a second area essentially perpendicular to the axis of rotation, wherein the first contact surface and the second contact surface have different areas; This application describes also a method of joining work pieces, a product comprising joined pieces, and the use of such friction stir welding tool.
