  • Patent number: 11738402
    Abstract: Method for scanning a workpiece surface (2A) of a metal workpiece (2), in which a blowtorch (3) having a welding wire electrode (4) is moved relative to the workpiece surface (2A) to determine scanning values and a wire end (4A) of the welding wire electrode (4) is repeatedly moved towards the workpiece surface (2A), in each case until contact with the metal workpiece (2) at a scanning position (P) on the workpiece surface (2A) of the metal workpiece (2) is detected, and the wire end (4A) of the welding wire electrode (4) is subsequently moved back, the blowtorch (3) detecting scanning values (d) at scanning positions (P), at least in some cases multiple times, to determine scanning measurement errors.

  • Patent number: 11666982
    Abstract: 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.

  • Patent number: 9786198
    Abstract: The invention relates to a method and a device (1) for simulating an electrode welding process having an electrode holder simulator (2) and a simulated electrode (3) arranged thereon, a simulated workpiece (4), an input device (6), an output device (7) and a control device (10). For the ideal training of an electrode welding process under conditions as real as possible, the control device (10) is connected to a memory (11) for storing parameters (Pi) of an ideal motion of the electrode holder simulator (2) during an ignition process and is designed for detecting the parameters (Pr) during an actual motion of the electrode holder simulator (2) and comparing them to the stored parameters (Pi) of the ideal motion of the electrode holder simulator during an ignition process and displaying the deviations between the parameters (Pr) of the actual motion and the parameters (Pi) of the ideal motion in the output device (7).
