A welding assembly having a support part, of a material that is absorbent to a laser radiation, and an attachment part, with at least one collar piece that is transparent to the laser radiation. The support part and the at least one collar piece have a first joining area and a second joining area, which together form a joining region. The surface contours of the joining areas deviate from one another, and so, when the welding assembly is being joined together, the collar pieces are deformed while they come to bear closely against the support part. The attachment part is formed in such a way that it can be taken up by a receiving mandrel and positioned with respect to the support part and pressed against it by means of the receiving mandrel.

Welding assembly and method for producing a welding assembly

The device comprises a welding unit with a tube (), a laser radiation unit () radiating in direction of the tube axis (), and a mandrel () which is connected to the tube () via a holding unit which is formed, e.g., by two spacer elements () and which is coaxially arranged relative to and in the tube (). The tube () and the circumferential surface of the mandrel () are reflective of the laser radiation of the laser radiation unit () such that through multiple reflections between the tube () and the mandrel () the laser radiation is deflected toward the beam output-side tube end () and is shaped annularly.
