A welding machine for welding free ends of bar conductors of a stator of an electrical machine, in particular an electric motor, includes a support structure for directly or indirectly fastening the stator. The support structure has a welding mask that can be opened and closed. The welding device is in particular a laser welding device. The welding device is arranged above the support structure. The support structure can be moved between a closed position and a loading position. A first side of the welding mask faces the welding device in the welding position and faces downward in the loading position. The welding machine allows free ends of bar conductors of a stator of an electrical machine to be welded while at the same time the stator is protected against contamination.

The present invention discloses an adaptive and rapid repairing device for single roller, which includes a working module and a mechanical arm module, which are fixedly connected, where the mechanical arm module is connected with a movable module; the working module includes a supporting frame, symmetrical dovetail grooves are opened in two sides of the supporting frame, the dovetail grooves are movably connected with four sliding supports symmetrically arranged along the supporting frame; a connecting rod support penetrates the two through holes opened in the top of the sliding support, the top end of the connecting rod support is hinged with a long connecting rod; the supporting frame is provided with a worm gear mounting support, the worm gear mounting support is equipped with worm gears and worms through rotating shafts, and the worm is fixedly connected with an output shaft of a worm motor.

In various examples, a computer-implemented method of generating instructions for a welding robot. The computer-implemented method comprises identifying an expected position of a candidate seam on a part to be welded based on a Computer Aided Design (CAD) model of the part, scanning a workspace containing the part to produce a representation of the part, identifying the candidate seam on the part based on the representation of the part and the expected position of the candidate seam, determining an actual position of the candidate seam, and generating welding instructions for the welding robot based at least in part on the actual position of the candidate seam.

A system for automatically brazing joints in a manifold has a loading station, a brazing station, and a cooling station. The brazing station has a plurality of brazing torches moveable to a joint in the manifold to braze the joint. First, second and third fixture frames extend from a common rotatable platform. The platform rotates each of the fixture frames to each of the loading station, brazing station, and cooling station in turn. The fixture frames support manifolds with joints requiring brazing. The torches are disposed on a lifting platform that lifts the torches up to a desired joint. The lifting platform is disposed on a sliding platform that slides the torches horizontally to the desired joint. The torches surround the joint and braze it from all sides simultaneously. While brazing is being performed at the brazing station, loading and unloading of manifolds may be done at the loading station, and cooling of already-brazed manifolds may take place at the cooling station.

Methods for fabricating high-strength aluminum-boron nitride nanotube (Al—BNNT) wires or wire feedstock from Al—BNNT composite raw materials by mechanical deformation using wire drawing and extrusion are provided, as well as large-scale, high-strength Al—BNNT composite components (e.g., with a length on the order of meters (m) and/or a mass on the order of hundreds of kilograms (kg)). The large-scale, high-strength Al—BNNT composite components can be made via wire-based additive manufacturing.

A scanner controller analyzes a position instruction in which a position in a world coordinate system and a position in a local coordinate system of a path of laser light are associated with each other and creates a movement command for a drive unit of a scanner based on the position of the local coordinate system. Further, the scanner controller calculates the current position of the scanner in the local coordinate system based on the position and attitude of a robot in the world coordinate system and the position in the world coordinate system in accordance with the position instruction. When the distance between the calculated position of the local coordinate system and the position in the local coordinate system in accordance with the position instruction is below a predetermined threshold, the scanner controller then determines to start machining and performs control of a drive unit of the scanner.
