Title:

WELDING UNIT AND WELDING METHOD BY WHICH AT LEAST TWO DIFFERENT WELDING PROCESSES MAY BE COMBINED

Document Type and Number:

Japanese Patent JP2011200937

Kind Code:

A

Abstract:

To provide a welding unit and a welding method in which the input of heat or energy is adjustable as independently from each other as possible.

At least one controller, a welding power supply 2 and optionally, a wire supply unit are arranged in a welding device 1. The welding torch unit 29 comprises at least two separate welding burners 10, 35 to carry out at least two independent separate welding processes. 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 a 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 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.
