A method is provided for the production of an electrical or electronic component having a conductor element with two contact points and a plastic structure injection-molded thereon. A strip-type metal substrate, having multiple conductor element blanks and a carrier structure, is provided. Grooved depressions are produced on all peripheral surfaces of the blanks on a texturing section with one or two laser light sources. With a single laser light source the grooved depressions are produced on at least two primary peripheral surfaces which adjoin one another and form a common edge such that a multiplicity of the grooved depressions extends without interruption continuously into the primary peripheral surfaces. A conductor element blank is separated from the carrier structure. The resulting conductor element is encapsulated with plastic by injection molding on all peripheral surfaces within a section to be encapsulated. The plastic structure thereby formed extends into the grooved depressions.

An apparatus includes a set of pre-welding electrodes including a shape-forming electrode having a contact face. The contact face has a shape-forming structure shaping a cross-section of a first segment of a first wire with a pre-welding shape upon compression of the contact face against the first segment. The pre-welding shape has a reentrance accommodating a second segment of a second wire to be welded to the first wire.

An ultrasonic welding method includes welding workpieces by applying ultrasonic vibration to the workpieces, wherein in the welding, the workpieces are vibrated at an amplitude smaller than an amplitude of the ultrasonic vibration.

A method is provided for monitoring a laser welding process for welding two workpieces of metallic material, particularly copper or aluminum, preferably bar conductors, by using a laser beam, particularly for monitoring a plurality of identical laser welding processes for welding two identical workpieces with the same laser power and the same welding duration of the laser beam. During the welding, the laser beam is directed onto adjacently disposed end faces of the workpieces to melt a fusion spot at the end faces then solidifying to form a weld bead. During the welding, the solidification duration from turning off the laser beam until solidification of the fusion spot is determined, the determined solidification duration is compared with a setpoint solidification duration predetermined for pore defect-free welding, and if the determined solidification duration falls below the predetermined setpoint solidification duration, the solidified weld bead is classified as defective.

A method performed during a run-in-hole process for a casing section includes applying pressure to a cable against an outer portion of the casing section. Additionally, the method includes ultrasonic welding the cable to the outer portion of the casing section while the pressure is applied to the cable against the outer portion of the casing section.

The particle-liquid mixture contains a plurality of types of solid particles and a base metal in a liquid form, and the plurality of types of solid particles at least includes reactive particles reactable with the base metal and non-reactive magnetic particles. A first magnetic field is applied to the particle-liquid mixture to magnetically disperse the plurality of types of solid particles in the liquid base metal to form a particle-liquid dispersion; and a second magnetic field is applied to cure the particle-liquid dispersion to allow reactions between the reactive particles and the base metal.

A special-shaped joint includes at least one connection terminal (1) for connecting an electrical device, and at least one wire (4). The connection terminal is connected to a core (2) of the wire.
