摘要： A device for the laser welding of a tube (14) along its inner circumference with a probe (1) that can be inserted in the tube (14) has within the probe (1) devices (73-76) with which a part of a stream of shield gas flowing within the interior of the probe is divided off before it reaches an outlet opening (45) for a focused and deflected laser beam (59) and is conducted to the outer surface of the probe (1) with an axial flow component directed toward the outlet opening (45). By this means, any precipitation of welding material in the vicinity of the outlet opening (45) and in the interior of the probe (1) is reduced.

摘要： A process and device for the laser welding of a tube (14) along its inner circumference with a probe (1) that can be inserted in the tube (14) has for the focusing and deflection of a laser beam (57) propagated within the probe (1), mainly along its longitudinal axis (10), at least one optical element (41, 65), which generates a deflected laser beam (59) focused on a focal point (F) lying outside the probe (1), the direction of whose propagation is oriented obliquely relative to the longitudinal axis (10). By this means, both the thermal stress on the deflecting elements (41, 65) mounted within the probe (1) and any precipitation of welding material in the interior of the probe (1) are reduced.

摘要： A method of simultaneously cutting and welding metal, especially relatively thin sheets of metal, utilizing laser energy. The invention uses surface tension in the globule created at the site of the impingement of the laser beam on the work to form finished edges on both sides of the line of cut. A laser beam surrounded by a thin shield of inert gas is used, the gas removing some of the molten metal but leaving sufficient to form the beads which comprise the finished edges on both sides of the cut, and also preventing oxidation of the beads.

摘要： Laser machining a work piece in an environment that is non-reactive to the material of which the work piece is made. In particular, the laser machining apparatus includes a chamber for readily receiving a work piece and means for moving the work piece along its X, Y, and Z axes with respect to the laser beam, while maintaining the purity of the machining environment. To this end, the machining chamber is mounted upon means for driving the machining chamber along X and Y axes. The machining environment is maintained within the machining chamber and a sealing means taking the form of a plate having a substantially flat surface, that is disposed of a substantially uniform distance from the peripheral edge of the machining chamber, so that the machining chamber may be driven without resistance by the moving means. The work piece is moved along the Z-axis, by means comprising a mounting plate rotatively disposed within the machining chamber and adapted to be coupled with drive means, whereby the mounting plate and the work piece secured thereto may be rotatively disposed with respect to the laser beam.

摘要： A laser processing apparatus (10; 110; 210), in particular for cutting and welding, including a focusing head (12; 112; 206) for focusing the beam on the work area (13, 13a; 113; 207) of the workpiece (15; 118; 209), and a nozzle (17) with a conduit (21; 120; 220) for directing a jet (18; 122; 213) of assist gas at a supersonic speed at least close to the work area (13, 13a; 113; 207). The work area (13, 13a; 113) is preferably covered by the walls of the conduit (21; 120) located downstream from the nozzle (33a, 33b, 33c; 132). To ensure optimum working conditions of the apparatus, the nozzle (217) is preferably supported for rotation about the focusing head (206), and is so controlled that, at least at the work area (207), the conduit is maintained tangent to the work path (T).

摘要： Oxygen is included in auxiliary gases, and zinc-plated steel plates (3a, 3b) with no blow holes can be welded. As the auxiliary gases, an oxygen gas bomb (4a) for O2 is provided in addition to an argon gas bomb (4b), argon gas and oxygen gas are mixed in a mixer (6), the mixture is delivered to a working head (7) and injected to a working point (9) via a nozzle (8). Oxygen oxidizes zinc of the zinc-plated steel plates (3a, 3b) to produce zinc oxide and zinc peroxide, which do not evaporate, the spatters are decreased in quantities and laser welding with a fewer blow holes can be performed.

摘要： Described is a device for laser-welding pipes (14) round the inside of the pipe ends, with a probe which can be inserted in the pipe (14) and with at least one imaging element (41, 65) to focus and deviate a laser beam (57) travelling inside the probe (1) substantially along the longitudinal axis (10) of the probe (1). The imaging elements (41, 65) produce a focussed, deviated laser beam (59) at a focal point (F) lying outside the probe (1), the direction of propagation of the beam being inclined at an angle to the longitudinal axis (10). This reduces the thermal load on the imaging elements (41, 65) inside the probe (1) as well as the tendency of the welding materials to deposit on the inside of the probe.
