Embodiment Construction

[0033]figure 1 An industrial system 1 is shown with a welding system 2 which is used to weld at least one metal component 5,6. In this case, at least one metal member 5, 6 is connected to at least one welding connection 7. The at least one welding connection 7 is, for example, a welding point and / or a weld seam. In this case, the two metal members 5, 6 are connected to each other, or only two edges of one of the members 5, 6 are also connected to each other.

[0034]The industrial system 1 is, for example, a production line for vehicles, furniture, buildings, etc., in which metal members 5, 6 are welded. To this end, the welding system 2 has a welding control device 10, a device 20 for guiding a welding tool 21, a detection device 30 and an operating device 40, which is implemented as a resistance welding tool and has two welding electrodes 22, 23. The equipment 20 is controlled by the control device 25. Furthermore, communication lines 41 to 45 are provided, and these communication li...

Abstract

The present invention relates to a welding control device of a welding tool and a method of force adjustment of a welding tool. A welding control device (10) for a welding tool (21) and a method for force adjustment of a welding tool (21) are provided. Welding Control Device (10) at least one electrode (22, 23) of the welding tool (21) applying the force to the at least one member (5, 6) when thewelding connection (7) is made, wherein the force adjustment module (11) outputs at least one rotational speed expectation (N _ S) to the driving device (26) of the welding tool (21) so as to adjust the driving of the welding tool (21) with the rotational speed regulator (261) of the driving device (26) to apply force (fs( T); FS _ ACT).

Description

Technical field[0001]The invention relates to a welding control device for a welding tool and a method for adjusting the force of the welding tool.Background technique[0002]In order to connect metal parts by welding, welding tools are used. For example, in industrial systems (Anlagen), especially in production lines for vehicles and the like, metal parts (especially plates) are connected by welding by means of welding tools. In automated body assembly workshops, welding tongs with electrode caps on welding electrodes are used as welding tools. In the case of resistance welding, the component to be welded is pressed at the location to be welded using the two welding electrodes of the welding tongs. Thus, a circuit is constructed in which a welding core is constructed between components using a specific current characteristic curve. In the case of spot welding / resistance welding, the constant quality of the welding point is very important.[0003]Such welding tongs are constructed, for ...
