Patent number: 11815877Abstract: A method for automatically determining optimum welding parameters for carrying out a weld on a workpiece carries out test welds on test workpieces along test welding tracks, and at each test weld a welding parameter is changed automatically along the test welding track from a predefined initial value to a predefined final value. Each resulting test weld seam is measured along the test welding track with a sensor, and a sensor signal is received. A quality parameter characterizing each test weld seam is calculated from the sensor signal. A quality function for characterizing the test weld seam quality in accordance with the changed weld parameters is calculated from the quality parameter. An optimum quality function is ascertained, and the values for the optimum welding parameters are defined based on each quality parameter at this quality function optimum and the corresponding test weld track locations and saved.Type: GrantFiled: May 6, 2019Date of Patent: November 14, 2023Assignee: FRONIUS INTERNATIONAL GMBHInventors: Manfred Schoerghuber, Bernhard Moertendorfer, Daniel Angermayr, Helmut Ennsbrunner

Patent number: 10821537Abstract: A method for establishing welding parameters for a welding process guides a welding torch along a predetermined welding path over the workpiece to be worked and sets welding parameters based on the respective path position for workpiece working. Before establishing the parameters, ideal parameters are determined by test welding processes on test workpieces along test welding paths, with a respective specific test workpiece position and arrangement relative to the gravitational acceleration vector and a specific tangential vector of the test path, and are stored. The parameters at the respective path position are established based on workpiece position and arrangement at the time relative to the welding path gravitational acceleration vector and tangential vector at the time by interpolation of the stored ideal parameter values for the determined positions and arrangements of the test workpieces relative to the gravitational acceleration vector and the specific tangential vectors of the test paths.Type: GrantFiled: July 12, 2017Date of Patent: November 3, 2020Assignee: Fronius International GmbHInventors: Helmut Ennsbrunner, Daniel Angermayr, Manfred Schoerghuber, Bernhard Moertendorfer

Patent number: 7256368Abstract: The invention relates to a welding method involving the use of a non-fusing electrode (12) according to which the electrode (12) is provided with power from a power source once the arc (11) between the electrode (12) and the workpieces (13, 14) to be joined has been ignited. The invention also relates to a tack welding method. The aim of the invention is to improve the quality of the weld seam in the starting phase of the welding process. To this end, the invention provides that before the actual welding process, a start program (22) is performed without the introduction of a filler material during which the electrode (12) is supplied with pulsed power in the form of current or voltage pulses over a presettable length of time (23) whereby causing the liquid molten bath to oscillate or vibrate, and that after the execution of the start program (22), the actual welding process is carried out during which the electrode (12) is preferably supplied with constant power.Type: GrantFiled: March 18, 2003Date of Patent: August 14, 2007Assignee: Fronius International GmbHInventors: Josef Artelsmair, Bernhard Mörtendorfer

Patent number: 7009143Abstract: The invention describes a method of brazing workpieces (16) with a torch (10), in particular a plasma or welding torch, having an electrode (28), in which a transmitted and/or non-transmitted working arc supplied with power from a power source or a current source (2) is produced in order to generate a plasma beam from a delivered plasma gas, whereby at least one filler material (38) is fed to the seam region of the workpieces (16) to be joined. The filler material (38) is connected to the or to another power source or current source (39). To this end, one potential (40) of the power source or current source (39) is applied to the filler material (38) and the other potential (35, 41) to the workpieces (16). The power source or current source (39) is regulated in such a way that when the filler material (38) is lifted off the workpiece (16) an arc is prevented from being generated.Type: GrantFiled: January 31, 2002Date of Patent: March 7, 2006Assignee: FRONIUS International GmbHInventors: Bernhard Mörtendorfer, Martin Gatterbauer

Patent number: 6831251Abstract: The invention relates to a method of feeding welding wire (13) from a wire supply reel (14) to a welding torch (10), having at least one welding wire feeder (27) and an apparatus, in particular another welding wire feeder (28), for applying a feed force, in particular a main drive (29) and an auxiliary drive (30), whereby a feed force or a pressure force, acting on the welding wire (13) between the welding wire feeders (27, 28) is detected by a detection means, in particular a sensor, and compensated or limited. A deflection or lateral deflection of the welding wire (13) is detected on the basis of the feed force or pressure force on the welding wire (13) between the welding wire feeders (27, 28), in particular the main drive (29) and the auxiliary drive (30), and this deflection is used as information for regulating at least one of the welding wire feeders (27, 28).Type: GrantFiled: September 20, 2002Date of Patent: December 14, 2004Assignee: Fronius International GmbHInventors: Josef Artelsmair, Michael Brunner, Bernhard Mörtendorfer
