Embodiment approach

[0069] 1. A method for marking a workpiece surface (2A) of a metal workpiece (2), wherein a welding torch (3) comprising a welding wire electrode (4) is guided along the workpiece surface (2A) to be marked, while the welding wire electrode ( The wire end (4A) of 4) moves towards and away from the workpiece surface (2A) to be marked, wherein the voltage (U) present at the wire electrode (4) and / or the current (I) flowing through the wire electrode (4) An electrical spark is generated causing material removal and / or material modification of the workpiece surface (2A) of the metal workpiece (2) to mark the workpiece surface (2A).

[0070]2. The method according to embodiment 1, wherein the wire electrode (4) comprises an additive material which can be melted during the welding process.

[0071] 3. The method according to embodiment 1 or embodiment 2, wherein the wire end (4A) of the wire electrode (4) is repeatedly moved towards the workpiece surface (2A) until a short circuit oc...

Abstract

The invention relates to a method and a device for marking a workpiece surface (2A) of a metal workpiece (2), wherein a welding torch (3) with a fusible wire electrode (4) is guided along the workpiece surface (2A) to be marked, and The wire end (4A) of the fusible wire electrode (4) is moved towards and away from the workpiece surface (2A) to be marked. The voltage (U) applied to the wire electrode (4) and / or the current (I) flowing through the wire electrode (4) generates an electrical spark, causing material to be removed from the workpiece surface (2A) of the metal workpiece (2), thereby marking Workpiece surface (2A).

Description

technical field [0001] The invention relates to a method and a device for marking the surface of metal workpieces, in particular metal workpieces which are subsequently welded. Background technique [0002] There are a variety of conventional methods for marking items. Component surfaces can be marked by material removal, material application or material change. For example, electrical, chemical, or laser-based marking methods can be used to remove material from the surface of a part to identify the part of interest. FR2556639A1 describes an exemplary electrical method for engraving a workpiece. [0003] Marking is also useful in many application scenarios for workpieces or components that are to be welded. However, conventional welding systems or welding methods do not offer the option of marking workpieces before or after performing the welding process without additional technical outlay. US2011 / 0220619A1 describes an exemplary welding system. Contents of the inventi...
