Embodiment Construction

[0024] Figure 1A shows a schematic block diagram of a typical welding method according to the prior art, wherein in a first step 1' first a first workpiece and a second workpiece are clamped in a fixture in such a way that they are each joined by their The surfaces are in contact with each other. Then in a second step 3' the first and second workpieces are driven into a common rotational movement around a rotational axis by means of a drive and the actual welding process takes place. In this case, a welding beam, in particular a laser beam, is aimed at the contact point of the first and second workpieces, whereby the welding beam is moved along the periphery of the contact point by the rotational movement and thus generates a The weld seam produces a solid and fully circumferential welded connection between the first and second workpieces.

Abstract

The invention relates to a welding method, in particular a laser welding method, for joining a first workpiece (10) and a second workpiece (11), wherein in a first method step (1) the first and second workpieces are (10, 11) are brought into contact with each other, wherein in a second method step (2) a desired welding distortion is ascertained, wherein in a third method step (3) the first welding a first and a second workpiece (10, 11) to each other, and / or causing said first and second workpiece (10, 11) to rotate about an axis of rotation (16) at a rotational speed in a third method step (3) Rotation, wherein in the third method step the first and second workpieces (10, 11) are welded together as a function of the rotational speed.

Description

Background technique [0001] This method is generally known. For example, a device and a method for laser welding a first workpiece and a second workpiece are known from publication DE 10 2006 015 383 A1, wherein the device comprises a laser source and a sensor for process monitoring of the welding process . The process monitoring is used here in particular to monitor the welding depth, which is detected in real time by an optical camera as a sensor and used as an adjustment variable for the laser source. The determination of welding distortion is not set in this method. Contents of the invention [0002] Compared with the prior art, the welding method according to the invention, the welding device according to the invention and the connection element according to the invention have the advantage that a desired or necessary welding distortion is obtained before the welding process, the welding distortion Converted during the welding process. This has the result that with ...
