    摘要： A method and a welding device for performing a welding process on a workpiece by a welding torch, uses a melting welding wire, which is arranged on a wire coil and may be supplied to the welding torch via a hose package, wherein different welding wires and different welding parameters are used depending on the geometry of the workpiece. A welding wire formed by the different interconnected welding wires in lengths depending on the geometry of the workpiece is arranged on the wire coil, so the welding process may be performed without interruptions using the different welding wires and the different welding parameters by supplying to the welding torch the welding wire formed by the different interconnected welding wires from the wire coil.

    摘要： A tandem pulse arc welding control apparatus includes a voltage detector; a voltage setting unit; a pulse-peak-current-reference-value setting circuit; a pulse-base-current-reference-value setting circuit; an error amplifier that calculates a pulse-peak-current variation value and a pulse-base-current variation value; an adder that calculates a pulse-peak-current value; an adder that calculates a pulse-base-current value; a pulse-waveform selection circuit that outputs the pulse-peak-current value in a pulse peak period, and that outputs the pulse-base-current value in a pulse base period; and an output control circuit that controls a current value for a second welding wire. Because an appropriate welding voltage can be obtained with this configuration, a high welding quality can be realized.

    摘要： An electric arc welding apparatus comprising at least a first consumable electrode and a second consumable electrode movable in unison along a welding path between the edges of two adjacent, mutually grounded plates, a first power supply for passing a first welding current at a first low frequency between the first electrode and the two plates, a second power supply for passing a second welding current at a second low frequency between the second electrode and the two plates, where each of the power supplies includes a three phase voltage input operated at line frequency, a rectifier to convert the input voltage to a DC voltage link and a high frequency switching type inverter converting the DC voltage link to a high frequency AC current, an output rectifier circuit to provide a positive voltage terminal and a negative voltage terminal, and an output switching network operated at a given low frequency for directing a pulsating welding current at the given low frequency from the two terminals across one of the electrodes and the plates, and a circuit for independently adjusting the given low frequency so the value of the first low frequency of the first power supply is different from the second low frequency of the second power supply.

    摘要： An improved arc-welding process and apparatus for producing welded seams by means of band or flat strip electrodes. The apparatus of the invention uses at least two band or flat strip electrodes which overlap at least partially. The aformentioned flat strip electrodes are then welded by means of arc-welding in a common welding bath.
