A method and an apparatus for collecting powder samples in real-time in powder bed fusion additive manufacturing may involves an ingester system for in-process collection and characterizations of powder samples. The collection may be performed periodically and uses the results of characterizations for adjustments in the powder bed fusion process. The ingester system of the present disclosure is capable of packaging powder samples collected in real-time into storage containers serving a multitude purposes of audit, process adjustments or actions.

The invention relates to machines and methods for the separative machining of a plate-shaped workpieces. The machine includes a first movement device for moving the workpiece in a first direction (X), a second movement device for moving a machining head, which directs the machining beam onto the workpiece, along a second direction (Y), Between workpiece bearing faces there is formed a gap for the passage of the machining beam. In the machine, mutually facing side edges of at least two of the workpiece bearing faces are oriented non-perpendicularly and non-parallel with respect to the first direction (X).

Double magnetic coupling for two welding heads that work parallel and independent at the front and at the back, (N) and (S), in paramagnetic and diamagnetic materials.

A manufacturing method of a stator according to the disclosure includes a clamping process of clamping, among coil ends of segment coils assembled into a stator core, a pair of coil ends adjacent to each other in a circumferential direction, by a clamp jig that presses the pair of coil ends in the circumferential direction, and a welding process of welding the coil ends exposed through an opening portion provided in the clamp jig. The clamp jig includes a pressuring structure that increases a pressing force in a direction away from weld faces of the coil ends welded in the welding process, the pressuring structure being provided on at least one of sideward pressing faces that come into contact with side faces of the coil ends that are provided orthogonal to the weld faces.

Joining apparatus for joining joining elements onto workpieces, comprising a joining element holding device, which is configured to radially hold a joining element, and comprising a loading pin arrangement, which is configured to slide a joining element axially into a holding position in the joining element holding device, and/or to axially support the joining element during a joining process, wherein the loading pin arrangement has a loading pin, which is slidable by means of a loading pin actuator arrangement in the direction of the joining element holding device. The loading pin arrangement is here designed to variably establish a loading pin stroke of the loading pin between at least two stages, so that in a first stage the loading pin is displaceable less far in the direction of the joining element holding device than in a second stage.
