Definitions

  • the invention relates to a device according to the
  • the preamble of claim 1 (see, e.g., FR-A-2 229 493).
  • the rod-shaped electrode is switched as a cathode and used as plasma gas helium. This creates a very hot plasma that evaporates thin oxide layers. However, this is not the case with all light metal alloys.
  • a plasma torch which has two electrodes, one of which is connected to the positive pole of a voltage source, and the second electrode is connected to the negative pole of a voltage source.
  • the former electrode merely serves to build up an auxiliary sheet which extinguishes again after ignition of the main sheet.
  • the initial supply of inert gas replaced by the supply of a welding gas.
  • the apparatus according to GB 1 384 730 only one electrode is welded, namely with the electrode held at negative potential.
  • the apparatus according to GB 1 384 730 serves to build up a protective gas envelope, which corresponds in composition to the welding gas.
  • FR 2 229 493 describes a plasma welding machine with two electrodes, wherein the front electrode in the direction of movement is operated positively in order to rupture oxide layers, and the electrode lying behind negative to create the actual weld seam.
  • the electrodes are arranged parallel to each other.
  • GB 691 373 also discloses a device with two electrodes, which, however, are operated with an alternating voltage.
  • the GB 691 373 deals in particular with the task of avoiding a tearing of the arc at the zero crossings of the AC voltage.
  • GB 691 373 proposes to use a plurality of electrodes, wherein the respectively applied voltages of the electrodes have a phase difference to each other.
  • US 3 931 489 is concerned with the welding of thin steel sheets, which are bent by a "forming mechanism" into a tube whose adjacent, longitudinal edges are subsequently to be welded.
  • US Pat. No. 3,931,489 has the problem that the workpiece bent to form the pipe already has strong springing-up forces in those regions in which, when using a plurality of electrodes, that electrode is furthest away from the "forming mechanism". It is therefore the object of US Pat. No. 3,931,489 to design a multiple welding head so that it can be brought closer to the "forming mechanism", where the resilient forces of the steel sheet are still comparatively low. An indication of the generation of narrow and smooth weld seams while increasing the welding speed is also not apparent from US 3,931,489.
  • the aim of the invention is therefore to avoid these disadvantages and to propose a device of the type mentioned, which enables a high welding speed even with difficult alloys and with which it can also be ensured that resulting oxide layers are removed.
  • the proposed measures make it possible to connect the two rod-shaped electrodes to different poles of the voltage sources.
  • plasma pulses which are generated with an electrode connected to the positive pole of a voltage source
  • the oxide layers are torn open and with the subsequent plasma pulses, with the one with the negative terminal of a Voltage source connected and therefore connected as a cathode electrode are generated, the base material clean and welded with a large penetration, resulting in very narrow and smooth seams. It can be worked with a very high welding speed.
  • By locking the switching devices which only allow voltage pulses of about 1 to 5 milliseconds, it is ensured that only one electrode can be acted upon.
  • the workpiece to be machined can expediently be switched as the counterelectrode, but it is also possible to produce the nozzle, or the respective nozzle body, from an electrically conductive material and switch it as a counterelectrode.
  • both electrodes can also be switched as cathodes.
  • the required welding energy can be distributed to both electrodes and therefore they can be made thinner. This enables the production of very narrow images of e.g. only 9mm wide. With such devices can therefore be welded in hard to reach corners of workpieces, which greatly facilitates the structural design of such parts.
  • each plasma arc can be effected by means of a high-frequency pulse, when the height of the voltage of the individual voltage pulses does not exceed the respective breakdown voltage of the distance between the electrode and its respective counter-electrode. However, the ignition can also be triggered by correspondingly high voltage pulses exceeding the respective breakdown voltage.
  • the wear of the electrode connected to the positive pole which is subjected to higher stress, can be kept relatively low.
  • an ionization of the effluent from the nozzle plasma gas in the region between the electrode and the nozzle can be achieved due to an RF rollover and thus the ignition of an arc between the electrode and the workpiece can be achieved due to the applied DC voltage.
  • This also results in a very extensive protection of the plasma burner, since this is not burdened by the usual pilot arc.
  • a nozzle made of a highly electrically conductive material and their connection via a high-resistance electrical resistance to the workpiece connected to the pole of the voltage source is also advantageous in devices according to the invention, in which the positive pole of the voltage source is connected to the nozzle passing through the electrode ,
  • the features of claim 9 and 11 cause a constriction of the plasma, or avoid widening of the same due to the friction of the plasma in the air exiting at high speed, so that a very high concentration of energy is achieved.
  • a receptacle 1 which is made of an electrically insulating material.
  • this receptacle 1 are two holders 2, at the lower ends of which electrodes 3, 4 of a temperature-resistant material, such as e.g. Tungsten, used.
  • the holder 2 are made of a highly electrically conductive material and are provided with a central bore 5, which are connected in the upper and lower regions via radial bores 6 with chambers 7, 8, of which the chambers 7, each with a gas channel 109, 109 ', is supplied separately via the plasma gas, are connected, and the chambers 8, each with a discharge nozzle 9 9' are connected.
  • nozzles 9, 9 have conical inner walls, wherein the inner wall of the nozzle 9 extends substantially parallel to the conical end portion of the electrode 3, wherein the free end of the electrode 3 may be flattened.
  • the electrode 4 is formed in contrast to the electrode 3 is substantially dull.
  • a cooling channel 10 is provided in the receptacle 1, which from an inlet 11 to a penetrated by the holder 2 of the electrode 4 annulus 12 and of this, divided into two branch channels (Fig. 2) penetrated to another of the holder 2 of the electrode 3 Annulus 13 and from this leads to a spout 14.
  • connection of the two electrodes 3, 4, or their holder 2 can via screw caps 15, or if the gas channels 109, 109 'have electrically conductive walls, via this. In the latter case, the connection via connection nipple, via which gas is supplied, take place.
  • a tubular guide 16 is provided between the nozzles 9, 9 ', which is provided for guiding a serving as a supplementary wire wire.
  • the guide 16 is cranked.
  • the receptacle 1 can be made very narrow.
  • the electrode 3 extends in the position of use of the receptacle 1 substantially vertically and the electrode 4 includes with this an acute angle which may be 20 ° to 70 ° in the rule.
  • two identical electrodes 3 are provided, both of which enclose an angle with the vertical.
  • connection head 18 spring-loaded connection nipple 20 are held axially displaceable, to which a water supply line 21 and a water outlet 22 are connected to the supply and removal of cooling water, said spring-loaded connection nipple 20 with connected recording 1 in the inlet and outlet 11, 14th intervene.
  • the fixed connection nipple 23 engage with connected recording 1 in the inlets 25 of the gas channels 109, 109 'of the receptacle 1 a.
  • O-rings used for sealing.
  • an eccentrically arranged pin 26 is held in the connection head 18, which engages in a corresponding bore 27 of a receptacle 1. This ensures that a connection of a receptacle 1 to the connection head only in a certain position, in the just one proper flow through the gas and cooling channels is given is possible.
  • connection head 18 can be connected with different electrodes 3, 4 fitted recordings 1, wherein such a change can be easily performed.
  • Fig. 7 shows a detail of the nozzle body 9 for an electrode 3, which has a conical or substantially frusto-conical end.
  • the inner wall 27 of the nozzle body 9 is substantially parallel to the conical end of the electrode 3. This measure ensures that the plasma gas is directed obliquely against the axis of the nozzle 9 and therefore the tendency of the exiting plasma with increasing distance from the Mouth of the nozzle 9 due to the friction to expand the ambient air is counteracted and therefore results on a workpiece to be machined desirably only a small focal spot.
  • the conical nozzle bore 28 surrounding cold gas channels 29 are provided in the nozzle body 9, which are evenly distributed around the nozzle bore 28 concentrically arranged.
  • the axes of these cold gas channels 29, most of which are an odd number, e.g. 3, 5 or 7 are provided, generatrix of a conical surface whose axis is concentric with the axis of the nozzle bore 28.
  • These cold gas channels are open to the chamber 8 and open at the end face of the nozzle body.
  • the plasma gas flowing through these cold gas passages causes cooling of the nozzle body 9 and causes a further constriction of the plasma emerging from the nozzle 9 and thus a reduction of the focal spot and thus an increase in the energy concentration in the latter.
  • the supply of the chamber 8 with plasma gas via a gas channel 109, 109 ', the upper radial holes 6 of the holder 2, the central bore 5 and the lower radial holes. 6
  • Fig. 8 shows schematically the connection of the device according to the invention.
  • the electrodes 3, 4 are each connected to one pole each having a voltage source 31, 32 whose respective second pole is connected to a workpiece 30 via a respective switching device 33, 34.
  • the back electrode 3 in the welding direction is connected as a cathode and connected to the negative pole of the voltage source 32.
  • Typical values are e.g. a current of about 170A for a time of about 15ms and a break of about 3ms. During this time, the switching device 33 turns on and the connecting to the positive pole of the power source 31 electrode 4 is applied with ca: 250A for about 3ms.
  • each electrode 3 in the receptacle 1 it is also possible to use two electrodes 3 in the receptacle 1 and to each connect them to the minus pole of a DC voltage source 32 and apply them essentially alternately, although overlapping times may also be provided. In this way, since the load of each electrode 3 is correspondingly small, small-diameter electrodes 3 can be used, whereby the receptacle can be made very narrow.
  • the embodiment according to FIG. 10 differs from that according to FIGS. 1 and 2 in that helical ribs 35 are arranged in the chambers 8 which are connected to the gas connections via the gas channels 109, 109 ', between which helically extending channels remain through which the plasma gas flows to the nozzles 9, 9 '.
