A method for producing a primary material for a cutting tool, for example a primary material for a saw blade or a saw band, in which a band-shaped carrier of a metal carrier material and a wire of high-speed steel are continuously brought together along a lateral edge of the band-shaped carrier and transported into a welding device and the band-shaped carrier is welded to the wire along the lateral edge of the carrier to produce a bimetal band. The band-shaped carrier and the edge wire are welded to one another by at least a first welding device, which is arranged on one side of the band-shaped carrier, and at least a second welding device, which is arranged on the opposite side of the band-shaped carrier.

Physical vapor deposition target assemblies and methods of manufacturing such target assemblies are disclosed. An exemplary target assembly comprises a flow pattern including a plurality of arcs and bends fluidly connected to an inlet end and an outlet end.

An airfoil component for attaching to a cropped airfoil is provided. The cropped airfoil comprises a cropped airfoil attachment section and a cropped first side opposite a cropped second side, which each extend axially between a cropped first edge and a cropped second edge to define a cropped chord length. The airfoil component comprises a body having a component first side opposite a component second side. The body defines an attachment section for attaching the airfoil component to the cropped airfoil at the cropped airfoil attachment section. The attachment section extends axially between a component first edge and a component second edge to define a component chord length, and the attachment section is oversized with respect to the cropped airfoil attachment section such that the component chord length is longer than the cropped chord length. Systems and methods also are provided.

A welding system comprises a two manipulators and a controller. A first manipulator has a joint detection device and a first welding device, usually of the laser type while the second manipulator has a second welding device, usually of the arc weld type. The joint detection device is operative to read welding joint characteristics along a welding joint. The controller determines a corrected trajectory based on a predetermined welding trajectory and on the welding joint characteristics read by the joint detection device. This corrected trajectory is transmitted with a first time delay to the first manipulator and with a second time delay to the second manipulator. The second time delay is a function of a distance between the joint detection device and the second welding device. A corresponding method for welding components along a welding joint is also disclosed.

Two parts are joined along a joining gap disposed therebetween by welding by illuminating the joining gap with an energy beam through a mobile vacuum chamber which is moved, on the side to be welded, on the parts being joined along the joining gap and in which a vacuum is generated. The vacuum chamber forms a first vacuum chamber in which, during welding, a vacuum having a first pressure level is generated, and a vacuum having a second pressure level is generated in a second vacuum chamber which adjoins the first vacuum chamber directly at a chamber wall thereof and which, during welding, regionally covers the joining gap. The pressure levels in the two vacuum chambers are matched to one another or the first pressure level is raised to above the second pressure level by way of a pressure regulating system.

The fatigue strength of a lap-welded joint, wherein an overlapping portion of a first steel material and an overlapping portion of a second steel material overlap with each other, and an edge portion of the first steel material is welded to a front face of the second steel material with a weld zone extending along the edge portion, is improved. First, when a direction perpendicular to an extending direction X of the weld zone and parallel to a front face of the second steel material is defined as a reference direction Y, the lap-welded joint is restrained from moving in the reference direction Y, and the first steel material and the second steel material are restrained from moving in their sheet-thickness directions. In this state, a portion of the second steel material is heated such that a melted portion is formed in the portion of the second steel material.

The invention relates to the thermal creation of a part, including steps of: using at least one first and one second metal plate (30, 31), hollow-forming the first plate so as to form at least part of said inner wall, and hollow-forming the second plate (31) so as to form at least part of said outer wall. During the forming, the shapes of the first and second plates are adjusted such that they can be placed in contact with each other while leaving a space therebetween inside said periphery, and then the first and second plates are placed in a low-pressure and/or controlled-atmosphere chamber (65), where said plates are brought together and peripherally sealed together such that, in said space, a low-pressure and/or controlled-atmosphere enclosure is created.

Physical vapor deposition target assemblies and methods of manufacturing such target assemblies are disclosed. An exemplary target assembly comprises a flow pattern including a plurality of arcs and bends fluidly connected to an inlet end and an outlet end.

In manufacturing method of shunt resistor according to the present invention, at least one of first and second conductors that is thicker than a resistance alloy plate member includes a joining surface abutted to the resistance alloy plate member with their edges on one side in a plate-thickness direction being aligned with each other, a first inclined surface that is gradually located on one side in the plate-thickness direction from the joining surface toward the side opposite to the resistance alloy plate member in the plate-surface direction, and a first plate surface extending to the side opposite to the resistance alloy plate member in the plate-surface direction from the first inclined surface. Electron beams or laser is emitted to the joining surfaces of the conductor having the larger thickness and the resistance alloy plate member from one side in the plate-thickness direction to weld the joining surfaces.

A method for producing a component structure of two components includes subjecting the components to beam energy for melting in a contact region. A variation of beam current is set to melt the components in the contact region over a defined component depth less than the perpendicular distance between sides of the contact region. A defined beam current pulse is periodically imparted to the variation of the beam current, to melt the components at least approximately over the entire perpendicular distance between the sides of the contact region and to produce in the region of the second side weld regions of a weld root of the weld connecting the components projecting from the contact region and form a pattern which representative of a weld quality. Between the weld regions there is no melting of the components in the region between the defined component depth and the second side.
