Abstract:
A method for manufacturing a one-sided heat sink from a plurality of individual lamellas each including a base and a fin portion extending from the top surface base portion. The base portion is wider than the fin portion. The base portions of a plurality of lamellas are aligned such that the fin portions of each lamella extend in one direction and side surfaces of adjacent base portions face each other while the bottom portions form an even surface of the heat sink. A force is applied to side surfaces of the base portions of outermost lamellas such that the lamellas are urged into contact with each other. The bottom surfaces of the base portions are welded together.
Abstract:
A method of manufacturing a composite conductive component comprising the steps of providing at least two blanks of metallic material, said blanks consisting of dissimilar metallic materials; placing said blanks in edge to edge or in partially overlapping relationship with one another, solid state joining said blanks to each other, by rolling or welding, so as to form a composite body, rolling said composite body along the joint over the entire width of the composite body to reduce the thickness thereof, and cutting the rolled composite body across the joint to produce at least two composite conductive components, each comprising the metallic materials of said at least two blanks and having a joint between said at least two different metallic materials.A composite conductive component comprises at least a first portion of a first metallic material and at least a second portion of a second metallic material, said first and second metallic materials being dissimilar from each other is produced by the method. An electrical connector or conductor or a device for heat conduction comprises the composite conductive component.
Abstract:
The invention related to a platform made of the extruded self-carrying profiles supported by the supporting frame fixed to the inner interior walls. The platform floor is made either from the single individual profiles or is made from the pre-assembled or pre-fabricated segments to be joined together on the site. The platform parts are made of a light and rigid stiff material such as aluminium, aluminium alloys, preferably by extrusion or any suitable composite. The single profiles, the smaller pre-fabricated sections of light material are much easier to transport and assemble. Alternatively the platform is also provided with circumference floor movable segments mounted at its perimeter that might extend outside of the floor and thus allow elimination of gaps between the inner interior walls and the platform circumference. This prevents the falling through down e.g. the service tools and/or personnel.

Abstract:
A wrought aluminium material with improved damage tolerance while preserving the high strength of the material is disclosed. Furthermore, a cast aluminium material of a precipitation hardenable aluminium alloy is disclosed, the material comprising grains having two distinct zones with a first centre zone enriched in elements capable of reacting peritectically with aluminium and a second zone, surrounding the first zone, enriched in elements capable of reacting eutectically with aluminium.
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.
