Method for scanning a workpiece surface (A) of a metal workpiece (), in which a blowtorch () having a welding wire electrode () is moved relative to the workpiece surface (A) to determine scanning values and a wire end (A) of the welding wire electrode () is repeatedly moved towards the workpiece surface (A), in each case until contact with the metal workpiece () at a scanning position (P) on the workpiece surface (A) of the metal workpiece () is detected, and the wire end (A) of the welding wire electrode () is subsequently moved back, the blowtorch () detecting scanning values (d) at scanning positions (P), at least in some cases multiple times, to determine scanning measurement errors.

A method for providing a referenced distance signal which corresponds to the distance between a contact tip of a welding torch and a workpiece to be machined, includes adjusting an operating point on a predetermined welding characteristic, which is defined at least by a wire feed rate, a welding voltage and/or a welding current, and a CTWD distance between the contact tip and the workpiece; determining a target parameter value of at least one parameter dependent on the CTWD distance for the operating point; determining an actual parameter value of the at least one parameter by measuring at least one of the present wire feed rate, welding voltage and/or welding current; modifying the determined actual parameter value as a function of a calculated difference between the target parameter value and a predetermined reference value; and outputting the referenced distance signal corresponding to the modified actual parameter value to a position control system of a robot arm.

The invention relates to a method for determining a setpoint value (p) for the contact pressure of conveying rollers () of at least one device () for conveying a welding wire () of a welding device (), and a corresponding welding device (). In order to improve the determination of the setpoint value (p) for the contact pressure of each conveying device (), data of the defined parameters (P) together with data from additional parameters (P) relating to the configuration of the welding device () are stored in a database () together with the setpoint values (p), determined in each case empirically, of the contact pressure or a calculation rule for calculating the respective setpoint values (p) of the contact pressure, and the setpoint value (p) of the contact pressure of each conveying device () is determined empirically or by calculation depending on this defined parameters (P) and additional configuration parameters (P) from the database () and is indicated on at least one display ().
