A system for controlled induction welding of at least one weld seam area (A) of at least two surfaces of at least one workpiece is provided. The system comprises an inductor configured to be arranged in conjunction with the at least one workpiece, a processing means configured to generate an electromagnetic field by applying an alternating voltage to the inductor so as to inductively heat at least one of the surfaces so that the weld seam area (A) is welded together, simultaneously measure at least one parameter (P) of the at least one workpiece at least based on the generated electromagnetic field, detect a change of the at least one parameter (P), and determine a temperature estimation of the at least one workpiece based on said detected change.

An apparatus for fabricating a part, comprising a curved shaft; a build plate connected to the curved shaft; a motor; and a transmission connecting the motor and the curved shaft. The build plate moves along a curved path having a radius of curvature originating on an axis when the transmission transfers power from the motor to the curved shaft. Material deposited on the build plate along the curved path forms the part comprising a solid of revolution around the axis. In one or more examples, the part is an aircraft engine inlet.

A fluid system component can include a body that includes a multidimensional shape defined in orthogonal directions and layers stacked along one of the orthogonal directions, where at least one of the layers includes polymeric material and graphene nanoplatelets formed in situ from the polymeric material, and where the graphene nanoplatelets increase stiffness of the polymeric material.

A gas flow can be provided together with a liquid jet guided laser beam to remove accumulated liquid on the processing surface. The gas flow can be configured to have minimum interference with the liquid jet guided laser beam, while functions to blow away liquid generated by the liquid jet. Keeping the surface free from accumulated liquid can improve the efficiency of the liquid jet guided laser processing.

A method for thermally joining thermoplastic fiber composite components, including jointly covering thermoplastic fiber composite components to be joined, at least in the region of a joining zone, with a pressurization arrangement, which is flexible, at least in some section or sections, and extensive pressurization of thermoplastic fiber composite components to be joined by the pressurization arrangement, with the result that the fiber composite components are pressed against one another, at least in the joining zone. The fiber composite components are welded in the joining zone during pressurization. The pressurization is maintained by the pressurization arrangement until the joining zone solidifies. A cover is also disclosed, in particular a mold or diaphragm, for a pressurization device for thermally joining thermoplastic fiber composite components, and an apparatus for thermally joining thermoplastic fiber composite components.

A friction brake body for a friction brake of a motor vehicle, in particular a brake disk, includes a base body made in particular from gray cast iron and having at least one wear resistant layer formed on a friction contact surface of the base body. The wear resistant layer is made from ferritic-austenitic steel and includes an incorporated hard material particle, in particular finely distributed hard material particle.

A structural member includes a top sheet portion which has a first edge portion and a second edge portion facing the first edge portion, a wall portion which extends from the second edge portion in a direction intersecting the top sheet portion, and a closed cross-sectional portion which is provided in the first edge portion, in which the first edge portion is curved toward an inside of the top sheet portion in a plan view with respect to the top sheet portion, and when a distance from the first edge portion to the second edge portion of the structural member is referred to as a structural member width, the closed cross-sectional portion forms a closed cross section on a vertical cut plane of the structural member along a direction of the structural member width, the vertical cut plane of the structural member along the direction of the structural member width has an open cross section, and a shape of the vertical cut plane of the structural member including the closed cross-sectional portion is asymmetric with respect to a center of a length of the structural member width.
