    摘要: Hybrid welding process using a laser beam and an electric arc to produce a weld bead. The electric arc is established between an electrode connected to a first pole of a current source and at least one workpiece to be welded and connected to a second pole of a current source via at least one electrically conducting earth contactor in contact with the workpiece to be welded. To obtain effective welding, a contact is made between the earth contactor and the workpiece to be welded laterally and/or upstream of the point of impingement of the electric arc on the workpiece(s) to be welded, and considering the direction of formation of the welded joint, so as to balance the forces associated with the induced electromagnetic field acting on the puddle of liquid metal.

    摘要: A writing instrument is provided, including a writing tip, a reservoir containing a liquid ink, and a capillary transfer rod extending from a first end to a second end of the reservoir. The capillary transfer rod transfers the liquid ink from the reservoir to the writing tip. A capillary element having an orifice is slidably mounted around the capillary transfer rod so as to move freely in the reservoir. An outside edge of the capillary element comes into the immediate vicinity of an inside wall of the reservoir in such a manner that the capillary element comes substantially flush with an inside wall of the reservoir as it slides along the transfer rod.

    摘要: The invention relates to a method for the laser welding of metal parts that comprises generating a CO2 laser beam, dispensing a protection gas jet made of said gas or gas mixture in the direction of the junction plane between the parts, melting and evaporating the metal of the metal parts with the laser beam in order to generate a metal vapor capillary with the simultaneous generation of a metal plasma that propagates outside the metal vapor capillary and thus forms a metal plasma plume above said junction plane. The protection gas jet is further directed towards the metal plasma plume forming above the junction plane. The gas jet is preferably directed so that the latter comes flush with the top of the metal plasma plume and impinges on the part(s) at a location where the metal of said parts has not been molten by the beam.
