Embodiment Construction

[0021] figure 1 A welding device 1 or welding unit is shown for various processes or methods, such as MIG / MAG welding or WIG / TIG welding, or electrode welding methods, double-wire welding / front-back welding (double-wire / tandem welding) method, plasma or brazing method, etc.

[0022] The welding device 1 comprises a power source 2 with a power element 3, a control device 4, and a switching element 5 connected to the power element 3 and the control device 4, respectively. The switching member 5 and the control device 4 are connected to a control valve 6 arranged in a line 7 between the gas container 9 and the welding torch 10 or welding torch to deliver a gas 8, in particular a shielding gas such as carbon dioxide, helium or argon etc.

[0023] In addition, a wire feeder 11 commonly used for MIG / MAG welding can be controlled by the control device 4 so that additional material or welding wire 13 is delivered from a delivery drum 14 or coil via a delivery line 12 to the region ...

Abstract

The invention relates to a welding unit (27), comprising a welding device (1), with a welding torch unit (29) which may be connected thereto by means of a tube group (23, 28). At least one controller (4), a welding power supply (2) and, optionally, a wire supply unit (30) are arranged in the welding device (1). The welding torch unit (29) comprises at least two separate welding burners (10, 35), embodied for carrying out at least two independent separate welding processes. The invention further relates to a welding method, in which at least two different welding processes can be combined. According to the invention, such a welding unit (27) and welding method can be achieved, in which the amount of introduction of additional material and the heat or energy supply into the workpiece (16) may be adjusted as independently from each other as possible, whereby the first welding burner (10) is embodied for carrying out a welding process and at least one second welding burner (35) is embodied for carrying out a cold metal transfer welding process with a back-and-forth movement of a welding rod (32) and for synchronisation of the welding processes carried out with the at least two welding burners (10, 35).

Description

technical field [0001] The invention relates to a welding unit with a welding device to which a welding torch unit can be connected via a tube stack, in which at least one control unit and a welding power source and optionally a wire feeder are arranged unit, and the torch unit is formed by at least two separate welding torches for performing at least two independent, separate welding processes. [0002] The invention also relates to a welding method combining at least two different welding processes. Background technique [0003] The term "torch" is intended to include various conventional welding torches as well as laser welding torches and the like. [0004] In known welding methods, all parameters can be adjusted via input and / or output devices provided on the welding device. In this way, by adjusting various parameters, a suitable welding process such as a pulse welding process, a spray-arc welding process or a short-arc welding process can be selected. In addition, ...
