The invention relates to a heat-exchanger element for connection to tubes of a heat exchanger, the heat-exchanger element (1, 29, 32) consisting of a plurality of components (13, 14) welded to each other, and said components (13, 14) being interconnected by electron beam welding and being part of a heat exchanger head.

The invention relates to a method for orientating two workpieces in order to form a joining connection, wherein in a longitudinal orientation step the first workpiece is orientated relative to the second workpiece) along at least one of the workpiece edges by linear movement of at least one of the grippers relative to the other gripper and wherein the longitudinal orientation step is carried out during the transport of the workpieces from the provision station to the processing station. Furthermore, the invention relates to a manipulator which comprises a first gripper and a second gripper.

A method, apparatus, and system are provided to monitor and characterize the dynamics of a phase change region (PCR) created during laser welding, specifically keyhole welding, and other material modification processes, using low-coherence interferometry. By directing a measurement beam to multiple locations within and overlapping with the PCR, the system, apparatus, and method are used to determine, in real time, spatial and temporal characteristics of the weld such as keyhole depth, length, width, shape and whether the keyhole is unstable, closes or collapses. This information is important in determining the quality and material properties of a completed finished weld. It can also be used with feedback to modify the material modification process in real time.

Systems and methods of manufacture of radiator fins. In one embodiment, a radiator fin made of carbon fiber is provided. In one aspect, the radiator fin is made of carbon fibers forming an interlaced pattern. In another aspect, the interlaced carbon fiber radiator fin is attached directly to a heat pipe, the heat pipe connected to a heat source.

The invention relates to a method for manufacturing a housing of a turbomachine, in particular a gas turbine. The method comprises at least the steps: providing a housing blank, manufacturing a housing element, producing an assembly opening corresponding to the housing element in the housing blank, arranging the housing element in the assembly opening, and joining the housing element to the housing blank by means of a welding method. In addition, the invention relates to a turbomachine housing.

System and method for welding a precipitation-hardened superalloy, e.g., Nickel-based superalloy, article to produce a weld joint, wherein one or more sections are defined longitudinally within the entire length of the weld joint to be produced, melting of superalloy material adjacent the weld joint to be produced in one of the one or more sections is subsequently performed, by directing a power beam towards the section and longitudinally oscillating the power beam within the section, an intensity of the power beam and a frequency of oscillation of the power beam are selected such that the superalloy material adjacent the weld joint to be produced are caused to become uniformly heated and melt thereby producing the weld joint from the consolidation of the superalloy material so melted, where the weld joint is thereafter solidified by gradually reducing the power beam intensity while oscillating longitudinally the power beam within the section.

This disclosure relates to a battery assembly for an electrified vehicle and a corresponding method. An exemplary battery assembly includes a battery cell including a terminal, a busbar, and at least one first weld bead securing the busbar to the terminal. The at least one first weld bead is substantially Z-shaped.

Disclosed is a method for producing a blade for a turbomachine, in particular for an aero engine. The method comprises providing at least one blade airfoil with a first platform region and at least one blade root with a second platform region and joining the blade airfoil and the blade root at the respective platform regions by a friction welding method at a common joint region of the platform regions, the blade airfoil and the blade root being made of materials which are different from each other. Also disclosed is a blade which is and/or can be obtained by such a method.

A core manufacturing that includes stacking a plurality of electromagnetic steel plates in an axial direction; performing first welding on an inner surface of a through hole formed in a stack of the electromagnetic steel plates and continuous in the axial direction, the first welding being performed toward a first side in the axial direction which is one side in the axial direction; and performing second welding on the inner surface of the through hole, the second welding being performed toward a second side in the axial direction which is the other side in the axial direction.

A method of repair for a metallic part of an aircraft engine includes detecting a defect inside a bore of the metallic part wherein the defect represents a departure from an intended geometry of the bore, the bore having a diameter and defining a longitudinal axis, and wherein the defect is located within the bore at a depth of at least greater than one diameter along the longitudinal axis. The method also includes measuring a geometry of the defect, preparing a patch with a complementary geometry to fill the geometry of the defect, placing the patch in the bore with the complementary geometry of the patch seated against the geometry of the defect, directing a welding beam from outside the bore, through the bore and onto the patch to weld the patch to the bore, and removing a portion of the patch to provide the intended geometry for the bore.
