Embodiment Construction

[0030] figure 1 An industrial plant 1 with a welding device 2 is shown. The industrial plant 1 is, for example, a production line for vehicles, furniture, buildings, etc., in which metallic workpieces 5 , 6 are joined by welding such that a welded connection 7 is produced. In particular, however, the welded connection 7 can thus also be produced only on the workpiece 5 by connecting the two edges of the workpiece 5 to one another by means of the welded connection 7 . The workpieces 5, 6 can be selected from any weldable material, such as steel, aluminum, alloys thereof, and the like. Here, various materials can be combined arbitrarily.

[0031] The welding device 2 has a welding controller 10 , a device 20 for guiding the welding tool 21 , a detection mechanism 30 , an operating device 40 and a superordinate control device 50 which can control the welding device 2 and / or the industrial system 1 other components not shown. Such components are, for example, a transport mechani...

Abstract

The invention provides a welding controller and method thereof. The welding controller comprises a control mechanism for controlling a welding transformer and a welding tool of the welding equipment,wherein the welding tool is used to produce at least one welded joint on at least one workpiece and the welding transformer is configured for supplying the welding tool with a welding current for producing the welded joint, and the welding controller also includes a monitoring device for monitoring at least one welding variable by comparison of an actual welding process with a first desired welding profile of the at least one welding variable when producing a welded connection with the welding tool, wherein the first desired welding profile is not under the operating conditions of the weldingsystem was created, wherein the monitoring device is also configured to be monitored at least one weld size in addition, to evaluate at least a second target welding history made under the operating conditions of the welding equipment to judge whether or not the produced welded joint satisfies the quality requirements.

Description

technical field [0001] The invention relates to a welding controller for a welding device and a welding method for regulating the quality of the production of welded connections, which can be, for example, weld spots, weld seams or the like. Background technique [0002] Welding systems are used in automated vehicle construction for welding vehicles, such as the bodies of motor vehicles, trucks, aircraft, etc. Here as well as in other manufacturing plants, such as production lines for furniture etc., metal parts are joined by welding with the aid of welding tools of welding machines. The manufacturer of the vehicle must ensure that the correspondingly produced welded connections meet the quality specifications, so that, for example, one or more defective welded connections on the body of the vehicle do not cause damage to occupants of the vehicle in the event of an accident with the vehicle. be endangered, or render transportation unusable. [0003] Currently, the welding ...
