Title: Device for plasma-mig welding
IPC: B23K10/02
Filed: 1976-03-16
Abstract: 1490474 Plasma-arc welding systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 March 1976 [19 March 1975] 10498/76 Heading H2H [Also in Division B3] In apparatus for plasma-MIG welding wherein a non-consumable electrode and a contact tube for a consumable electrode are disposed within a plasma-forming gas housing and are respectively connected to drooping and flat voltagecurrent characteristic power supply sources, the drooping characteristic source is connected in series with the flat characteristic source whereby the open circuit voltage on the non-consumable electrode equals the sum of the open circuit voltage of the drooping source and the voltage on the consumable electrode, and, to improve plasma arc stability, the combined characteristic curve at a given voltage is steeper than the corresponding drooping source characteristic curve at the same voltage. Further, the plasma arc current intensity is reduced in the absence of consumable electrode voltage, so that by initially striking the plasma arc at low current intensity, to avoid non-consumable electrode  overloading, and subsequently striking the MIG arc, the plasma arc current intensity is automatically increased. Further again, in the event of extinguishing of the plasma arc, restriking is readily effected due to the voltage existing between the non-consumable and consumable electrodes. Preferably, the sources are D.C. and the non-consumable electrode and the contact tube are both of positive polarity. As shown, consumable electrode 11 is fed, by motor-driven variable-speed rollers 15, through a contact tube 13 disposed coaxially of a housing 3 and connected to a flat characteristic power supply source 33 in turn connectable to a workpiece 35. A non-consumable electrode 9 (e.g. of tungsten) is disposed, in a holder 8, eccentrically of the housing and connected to a drooping characteristic power supply source 29 connected in series with the source 33. The housing 3, holder 8 and contact tube 13 are water cooled through ducts 231, 23<SP>11</SP>, 251, 25<SP>11</SP>, 27<SP>1</SP>, 27<SP>11</SP>. Plasma gas, e.g. A, and shielding gas, e.g. A+CO 2 , are fed respectively through ducts 19, 21. In Fig. 3 (not shown), both the non-consumable electrode and the contact tube are disposed eccentrically of the housing, the nozzle of the latter does not have a constricting effect, the plasma arc being drawn around the energized consumable electrode to provide such effect. In Fig. 4 (not shown), the contact tube is disposed coaxially of the housing nozzle which acts as the non-consumable electrode and may be of tungsten or water-cooled copper.
