The marking device is further configured to mark the work surface in the shape of an assembly pattern. Assembly components are positioned on the assembly pattern to be assembled.

The disclosure relates to a method for erecting a supporting structure of a passenger transport system configured as an escalator or moving walkway. The supporting structure is constructed between two support points of an existing structure using a 3D welding robot system by depositing welding material.

A semiconductor device includes: a housing; a substrate inside the housing; first and second semiconductor circuits on the substrate; and first and second planar terminals electrically connected to the first and second semiconductor circuits, respectively, the first and second planar terminals stacked on top of each other, wherein each of the first and second planar terminals extends away from the housing.

A collar flange assembly welding fixture is disclosed, including a stand, a circular mount structure, and a support assembly which are configured to provide access to a front side and a back side of a collar flange assembly held by the support assembly. The stand has a plurality of circumferential bearings equidistant from an axis of rotation, the circular mount structure is rotatably supported by the circumferential bearings, and the support assembly is configured for mounting on the circular mount structure.

A method for producing a frame component for a door frame structure of an aircraft. A connecting zone is generated on a first and a second assembly surface of a connecting component in each case by generating a surface texture on the assembly surfaces, wherein the connecting component is formed from a metal material. The assembly surfaces of the connecting component are placed against a door frame member and against an attachment member, wherein the door frame member and the attachment member are each formed from a fiber-reinforced thermoplastics material. Furthermore, the connecting component and the door frame member are welded, and the connecting component and the attachment member are welded. A frame component and a door frame structure are also described.

A manipulator device such as a robot arm that is capable of increasing manufacturing throughput for additively manufactured parts, and allows for the manipulation of parts that would be difficult or impossible for a human to move is described. The manipulator can grasp various permanent or temporary additively manufactured manipulation points on a part to enable repositioning or maneuvering of the part.

A tow bar assembly for mounting to a vehicle, the tow bar assembly including a main beam configured to support a hitch receiver, the main beam comprising a bracket engaging portion at or near each end, a pair of brackets configured to securely mount to the vehicle, each bracket including a beam engaging portion, and a pair of fastening means for securing respective brackets at or near respective ends of the main beam, wherein each bracket and its respective beam bar engaging portion is configured to cooperatively interengage with a respective bracket engaging portion so as to locate and orient the bracket with respect to the main beam.

The present invention relates to a method for reducing or completely closing an opening of an inner contour 2 of a workpiece by means of a material melted by a laser deposition welding device 7, comprising the following steps: providing a workpiece 1 with an inner contour 2 having an opening defined by an edge section 11, forming a plurality of base webs 41 from molten material by laser deposition welding by starting at the edge section 11 of the inner contour 2 of the workpiece in such a way that the formed base webs 41 protrude from the edge section 11 at a predetermined angle, connecting adjacent base webs 41 by forming connecting webs 42 from molten material by laser deposition welding in such a way that a support structure 4 which comprises base webs 41 and connecting webs 42 is formed, forming a cover layer 5 of molten material connected to the support structure 4 in such a way that the opening of the inner contour 2 is reduced or completely closed.

A method of additive manufacture is disclosed. The method may include creating, by a 3D printer contained within an enclosure, a part having a weight greater than or equal to 2,000 kilograms. A gas management system may maintain gaseous oxygen within the enclosure atmospheric level. In some embodiments, a wheeled vehicle may transport the part from inside the enclosure, through an airlock, as the airlock operates to buffer between a gaseous environment within the enclosure and a gaseous environment outside the enclosure, and to a location exterior to both the enclosure and the airlock.
