Abstract
The invention describes a welding apparatus (1), which has a current source (2) for supplying electrical power to at least one electrode at a welding torch (10) and a control system (4) cooperating with the current source (2), linked to an input device (22) for entering settings for different welding parameters, several sensing means being provided for detecting various actual values of a welding process. At least one measuring device or system for sensing mechanical motion, in particular a welding wire displacement and/or a welding torch displacement or similar, is provided, which detects a surface structure of an object.

- 23. Method of controlling and/or regulating a welding apparatus, in which various actual values of a welding process are detected by various sensing means and used to control and/or regulate the welding process, characterised in that a motion is sensed, in particular a welding wire displacement and/or a welding torch displacement or similar, in such a way that a surface structure of an object is detected and stored and after a predefined measuring cycle time has elapsed the surface structure of the object is detected again, after which the detected surface structures are compared by an evaluation logic of the measuring system and a corresponding shift in the surface structures is recognised and detected.
