A camshaft for an internal combustion engine may include a shaft and at least one component thermally joined thereto. The at least one component may be connected via a component-side joining face to a shaft-side joining face of the shaft. At least one of the component-side joining face and the shaft-side joining face may include a predefined roughness introduced and hardened via a laser. The predefined roughness may define at least one track composed of a plurality of individual laser spots. Each of the plurality of individual laser spots may include a center point arranged offset to each other. The plurality of individual laser spots may respectively be arranged to overlapping each other.
