    摘要： An electron beam welding appliance (10), characterised in that it comprises: an electron gun (11) capable of generating an electron beam (FE); a focusing means (12) capable of orienting the electron beam along a first axis (Z); an arm (13) extending parallel to the first axis, the arm comprising: a means (14) for converting a density distribution of the electron beam in a plane perpendicular to the first axis (Z); and a means (15) for bypassing the electron beam along a second axis (X) substantially perpendicular to the first axis.

    摘要： A welding head for a welding apparatus, the head comprising an outer face attachable to a welding device such as an electron beam gun or laser, an inner face sealable to a workpiece, and an outer sealing ring and an inner sealing ring situated within the inner face and disposed on either side of an evacuatable region, wherein the inner face has a teardrop-shaped profile. Outer and inner sealing rings can be inflatable or formed from different materials, the outer sealing ring being formed from a material with a Shore hardness of between 50 to 70 and the inner sealing ring being formed from a material with a Shore hardness of 20 to 40. A bridging seal can extend from within the inner sealing ring to the outer sealing ring.

    摘要： The present invention relates to an apparatus for forming a three-dimensional article through successively depositing individual layers of powder material that are fused together so as to form the article, the apparatus comprising an electron beam source emanating an electron beam for fusing the powder material in a build tank, a hollow construction having an upper opening and a lower opening, means for moving the hollow construction between a first position and a second position, a synchronising unit for synchronising the movement of a powder distributor for applying the individual layers of powder material on the work table with the movement of the hollow construction so that the hollow metal construction is at the first position when fusing and/or heating the powder layer and at the second position when the powder distributor is distributing the powder material for forming the individual powder layers.

    摘要： A jig structure for manufacturing heat dissipation unit includes a main body, which internally defines a chamber and has a top forming an upper side thereof. The top defines at least one opening, on which at least one silicon dioxide layer is provided. The chamber is in a vacuum-tight state or maintains a positive pressure inert gas atmosphere therein. The jig structure for manufacturing heat dissipation unit can be used with a laser machining tool to provide a better environment and increased flexibility for laser machining or laser welding in manufacturing a heat dissipation unit.
