Stabiliser and method for manufacturing a stabiliser

The stabilizer (1) has two stabilizer components material-conclusively coupled with each other by a thermal joining and a circulating joining seam. A heat-affected zone resulted from the thermal joining is partially heat-treated after the coupling. Two stabilizer halves are connected by an actuator, where one of the stabilizer halves exhibits a flange (2) and a stabilizer profile that is material-conclusively coupled to the flange. The stabilizer profile is manufactured as a tubing profile (15) and/or a profile made of full material. An independent claim is also included for a method for producing a stabilizer.
