A method of joining includes applying braze to a braze reservoir in a first component. A second component is engaged to the first component, wherein a joint location is defined between the first and second components. A wicking structure provides flow communication from the braze reservoir to the joint location. The method also includes joining the first and second components together at the joint location by applying heat to the braze to flow the braze from the reservoir through the wicking structure to the joint location to form a braze joint at the joint location.

Resistance spot rivet welding systems, subsystems, and methods of use thereof are provided.

A tool arrangement is provided for accommodating portions of an optical tool in a park position, having an optical tool and having a housing with an opening suitable for accommodating portions of the optical tool in a housing interior, with a housing discharge connected to the housing in a fluid-conducting manner, and with a sealing sleeve arranged at the opening of the housing, wherein the sealing sleeve has a fluid-carrying line for adapting a variable fill volume of the sealing sleeve. In addition, a method is provided for accommodating portions of an optical tool in a park position.

In a cylinder device, a rod of which one end portion is joined to a piston in a cylinder and the other end portion protrudes from an opening portion of the cylinder includes a first member that is a hollow cylindrical member in sliding contact with a sliding contact member, and a second member that does not come into sliding contact with the sliding contact member. An outer diameter of at least a first member side end portion of the second member is smaller than an outer diameter of the first member. An inner peripheral portion of the first member is joined to an outer peripheral portion of the second member by friction weld joining.

A method, a component part of an end fitting and a preformed member for manufacturing a component part of an end fitting are disclosed. The method comprises the steps of, via an additive process, providing a near net shape (NNS) precursor corresponding to a component part of an end fitting layer-by-layer and subsequently performing at least one post NNS processing operation on the NNS precursor to provide the component part.

An apparatus and method for protecting an inner radial surface of a radial member of a turbomachine from corrosion are provided. The method may include shaping the inner radial surface of the radial member and a corresponding outer radial surface of a corrosion-resistant liner. The method may also include heating the radial member to increase a diameter of the inner radial surface of the radial member, and inserting at least a portion of the corrosion-resistant liner into the radial member. The method may further include attaching the corrosion-resistant liner to the inner radial surface of the radial member to thereby protect the inner radial surface of the radial member of the turbomachine from corrosion.

A tank including at least first and second portions connected by a connection ring and weld seams obtained by means of a friction welding method. The connection ring includes at least a first cylindrical portion fitted in the end of the first portion, at least a first shoulder protruding toward the outer zone of the tank relative to the first cylindrical portion and at least a first transverse web positioned approximately in the same transverse plane as the first shoulder. According to this configuration, the first cylindrical portion and the transverse web ensure that the forces generated by a friction welding head during the production of the weld seam which enables the tank to be closed are absorbed.

A laser irradiation apparatus includes a laser source configured to emit a laser beam to an object that is being conveyed to allow the object to be irradiated with the laser beam; a rotation detector configured to detect rotation of the object to obtain information on the rotation of the object; and circuitry configured to control laser irradiation onto the object based on the information on the rotation of the object.

The invention relates to a method of manufacturing a pipe having a connecting flange, wherein the flange part is welded to an end face pipe end and at least one protrusion of the pipe or of the flange part is provided in the region of the flange hub and contacts the inner wall of the other part on the joining together of the pipe and the flange part to cover the formed weld joint to the pipe interior; and wherein finally the pipe and the flange part are welded to one another.

A semiconductor device includes: a housing; a substrate inside the housing; first and second semiconductor circuits on the substrate; and first and second planar terminals electrically connected to the first and second semiconductor circuits, respectively, the first and second planar terminals stacked on top of each other, wherein each of the first and second planar terminals extends away from the housing.
