Embodiment Construction

[0032] figure 1 A welding device 1 or welding machine 1 is shown for various processes or methods, such as MIG / MAG welding or WIG / TIG welding, or electrode welding methods, twin wire / twin wire welding, plasma or brazing etc.

[0033] The welding device 1 comprises a power source 2 comprising a power unit 3 , a control unit 4 and a switching element 5 connected to the power unit 3 and the control unit 4 respectively. The switching element 5 and the control device 4 are connected to a control valve 6 arranged on a supply line 7 for a supply gas 8, in particular a protective gas such as carbon dioxide, helium or argon and the like, the supply line Between the gas reservoir 9 and the welding torch 10 or torch.

[0034] In addition, a wire feeder 11, which is often used in MIG / MAG welding, can be controlled by the control device 4, so that auxiliary material or welding wire 13 can be fed from a feed cylinder 14 or a coil via a supply line 12 to the region of the welding torch 10 ...

Abstract

The invention relates to a method for controlling and / or adjusting a welding process, using a melting electrode, wherein after ignition of an electric arc, a welding process, which is adjusted on the basis of several different welding parameters, is carried out by means a welding current source (2), said process being controlled or adjusted by a control device (4). The invention also relates to a corresponding welding device used to carry out the process. In order to create said method, wherein the thermal heat economy is adjusted and / or regulated and / or controlled in order to introduce heat into the workpiece (16), at least two different process phases are cyclically combined, said process phases having different inputs of energy via different material transitions and / or arc types, such as a pulse current phase (27) and a cold metal transfer phase (28) in order to influence or control thermal heat economy, particularly the introduction of heat into the workpiece to be processed.

Description

technical field [0001] The invention relates to a method for controlling a welding process with a melting electrode or a welding power source, wherein the welding process is carried out by the welding power source after ignition of an arc, which is regulated on the basis of several different welding parameters and controlled by a control device. [0002] The invention also relates to a welding device comprising a welding power source, a control device and a welding torch, wherein different welding parameters can be adjusted via input and / or output devices on the welding device or a remote control. Background technique [0003] In existing welding processes, all parameters can be adjusted through input and / or output devices provided on the welding equipment. When doing this, select an appropriate welding process, such as a pulse welding process or a spray arc welding process or a short arc welding process, and adjust the parameters accordingly. Alternatively, an appropriate ...
