A method for producing a rack for a steering gear may involve providing a toothed segment and a shaft segment aligned on a longitudinal axis and connecting the segments by axial joining faces by friction welding at a welding joint. For friction welding, the joining faces may be brought into frictional contact by an initial friction force, the segments may be rotated relative to one another, the joining faces may be mutually compressed by way of a contact pressure force until a predefined joining path has been reached by way of a welding force 10 to 20 times the initial friction force, thermal input friction may be performed by an input force 5 to 12 times the initial friction force, and the segments may be moved toward one another in an axial direction by the predefined joining path. The segments may be held in position without friction.
