    摘要: In order to enable highly efficient welding without the generation of weld defect such as undercut, overlap, and defective meeting angle, a plurality of additive wires (5a, 5b) are inserted into a melting pool (12) during horizontal welding, a unidirectional current is made to flow between the wires, and a magnetic field (9) is used to provide a magnetic field to the melting pool substantially in a direction perpendicular to a surface of a parent metal so as to cause the melting pool (12) to generate upward (antigravitational direction) Lorentz's force (11), whereby a molten metal is lifted upward to prevent dripping of the molten metal and to improve its bead shape.

    摘要: Plasma arc or laser cutting uses a mix of reactive (24a) and reducing gas flows (22a) to cut sheets (14) of stainless steel, aluminum and other non-ferrous metals. The reducing gas flow (22a) to the cut varies as a percentage of the total gas flow to maintain a reducing atmosphere down through the cut (12), but to leave a predominantly oxidizing atmosphere at the intersection of the cut (12) and the bottom surface (14B) of the sheet (14) being cut. In plasma arc cutting these flows can also be characterized as eithe a plasma gas flow (22a) that forms the arc, or a shield gas flow (24a) that surrounds the arc. The reactive gas is preferably a flow of air, oxygen, nitrogen, carbon dioxide or a combination of these gases. The reducing gas is preferably hydrogen, hydrogen 35, methane, or a mixture of these gases. For aluminum, the reactive gas is preferably air or nitrogen and the reducing gas is preferably methane or a mixture of methane and air. In laser cutting the reducing gases such as methane can be used by mixing them with reactive assist gases.

    摘要: An arc augmented laser welding apparatus has a welding head (10) which comprises a housing (14) a focusing system in the housing for focusing a laser beam through a laser opening in the housing onto a workpiece and a plasma torch nozzle (28) through which a plasma arc is established between an electrode (22) and the workpiece. A first power source (44) applies a high voltage across the electrode and nozzle to strike a pilot arc which is then sustained by power from a second source (42). A third power source (40) applies a high amperage signal to strike the main plasma arc between the electrode and the workpiece. The nozzle has a tip (33) which is adapted to constrict the plasma arc and restrict its impingement on the workpiece. The nozzle and the focusing system are arranged to cause the focused laser beam and the constricted plasma arc to impinge on the workpiece at predetermined relative positions which may coincide or may be slightly spaced apart. The power sources and the laser beam are controlled by a microprocessor in accordance with a predetermined programme in dependence on the type and thickness of material to be welded.

    摘要: The invention concerns a process for the machining of workpieces (10) using a laser beam (11) under protective gas, which has a vapourizing effect on the material, where an electric arc out of the laser beam (11) is guided in the proximity of the workpiece processing area (12) and whose ignition is controlled by a control device (13). In order to create a contact-less ignition process that thus avoids any additional movements on individual NC axes and presents the exact synchronization options of the electric arc ignition, of the laser beam effect and of the workpiece movements, when feedback that is harmful to machine control is avoided in the latter, the process is so effected that before the beginning of the machining in the processing area (12), a laser-induced plasma (14) is produced that is extinguished by the control device (13) after the ignition of the electric arc.

    摘要: The invention concerns a method of welding workpieces (10) by focusing a laser beam on the workpiece (10) which is moved in a relative manner, the laser beam causing material to vaporize. In addition to the laser beam (11), an arc (12) is used in the region of the workpiece (10) on which the laser beam acts. In order to improve welding results, the method is carried out on a workpiece (10) which, in a dielectric layer (15), has a dielectric-free surface track guiding the arc (12), the dielectric layer (15) completely covering the remaining welding area (14).
