In the process, an engagement recess (7, 21) can be formed in the open bundle end, an engagement pin (6, 20, 31, 38, 42, 44, 46, 49, 54) of the welding tool element (30, 37, 41, 43, 45, 48, 53) can engage into the engagement recess (7, 21), and at least a portion of the welding energy can be fed via the engagement recess (7, 21). A configured cable comprising individual cores (2, 15) with a receiving sleeve (4, 16, 33) is also presented, wherein the receiving sleeve (4, 16, 33) has an inlet opening (9) for a bundle (3) of the individual cores (2, 15), the receiving sleeve (4, 16, 33) has an end piece (5, 18) which is widened in relation to the inlet opening (9), and there is, at least also in the widened end piece (5, 18), a cohesive connection between at least one subset of the individual cores (2, 15) with respect to one another and/or between at least a subset of the individual cores (2, 15) and the receiving sleeve (4, 16, 33).

A soldering jig assembly for soldering conductors together includes a plate that may be positioned on a support surface. A pair of gripping units is provided. Each of the gripping units is coupled to the plate and each of the gripping units is selectively manipulated. Each of the gripping units engages an associated one of a pair of conductors.

An ultrasonic welding device includes a sonotrode with a sonotrode surface, a lateral slide with a lateral slide surface, a touching element with a touching surface and an insertion chamber for inserting joining parts. The insertion chamber is defined in a first axial direction (y) on a first side by the sonotrode surface and in a second axial direction (x) on a second side by the lateral slide surface and on a third side opposing the second side by the touching surface. Furthermore, the ultrasonic welding device includes a first receiving element with a first stop edge and a second receiving element with a second stop edge. The first receiving element and the second receiving element are arranged to be movable in relation to each other between a starting position and an end position.

Method for establishing a connection between an electrical connecting element for a motor vehicle on-board network and a cable of the motor vehicle on-board network in which the cable (2) is provided with a metallic stranded conductor (4), firstly the metallic stranded conductor is mechanically compacted in such a way that a flat area is formed, whereby during the compacting, a material bond is formed between strands of the stranded conductor (4), and subsequently, the connecting element is connected to the flat region in a material bond.

The present disclosure is directed to a multi-segment device, such as an intravascular guide wire. The multi-segment device includes an elongate first portion comprising a first metallic material, an elongate second portion comprising a different metallic material, the first and second elongate portions being directly joined together end to end by a solid-state weld, and a heat affected zone surrounding an interface of the weld where the first and second portions are joined together, wherein the heat affected zone has an average thickness of less than about 0.20 mm.

A method is provided for electrically conductively connecting a contact part to a conductor having a multiplicity of individual wires includes inserting the conductor into a cavity in the contact part and lowering a tool for friction stir welding onto the contact part. The tool for friction stir welding is moved on the contact part in a plane, thus giving rise to a planar cohesive connection between the contact part and the conductor. In this way, a direct cohesive connection of a stranded conductor and a contact part is produced without the need for an additional part such as a sleeve, for example, to prevent the stranded conductor from sticking out.

A cable treatment device including: an affixing device for reversibly securing to a circumference of a power cable a kinematic device having attachment structure for attaching to the affixing member, the kinematic device adapted to provide kinematic motion relative to the attachment structure, the kinematic motion being fully controllable through a plurality of force input connections, and a tooling device attached to the kinematic device, the tooling device adapted to receive said kinematic motion, wherein the kinematic device allows the tooling to move cross-sectionally relative to the extension of a power cable secured by the affixing device. Thereby, a well-controlled and reproducible process is achieved, employing a portable device being user friendly, while simultaneously reducing technician exposure to toxic particulates.

A guidewire for use in intravascular procedures has an inner coil that is radiopaque and an outer coil that is non-radiopaque at the distal end of the guidewire. The radiopaque inner coil is visible under fluoroscopy so that the physician can monitor the location of the distal end of the guidewire during a procedure. The inner coil and the outer coil can be formed from a single wire or a multi-filar wire. The inner coil and the outer coil can have any of the following cross-sections for enhanced torquability: I-beam; vertical rectangular; vertical ellipse; square; peanut shape; vertical hexagonal; horizontal hexagonal; and horizontal ellipse.

In an ultrasonic joining apparatus according to the present disclosure, an ultrasonic joining apparatus control board controls an operation of a lead set unit and a tension adjustment unit including a dancer roller to perform joining tension control processing. The joining tension control processing includes steps of: making a lead wire housing mechanism perform a rewinding driving of rewinding a lead wire in a lead cassette when the dancer roller reaches a lower limit adjustment position in a tension adjustment range; and making the lead wire housing mechanism perform a delivery driving of sending out the lead wire from the lead cassette when the dancer roller reaches an upper limit adjustment position in the tension adjustment range.
