ABSTRACT:
A method of producing an object of at least two parts movable relative to each other, one of which parts is essentially locked inside the other, and wherein a rolling bearing is disposed, between the two parts in races, which includes at least one row of rolling elements enclosed thereby, one of the parts consisting of at least two separate pieces of steel subjected to a hardening operation, wherein these pieces are placed against each other in a proper position to form a parting seam, and wherein the rolling elements are inserted and the two parts are held together in that position, and wherein a high-energy radiation welding means is passed over the seam and activated, while a rotary motion of the energy beam and the two parts are brought about to weld the two pieces together, characterized in that the steel pieces are subjected to a surface hardening with the regions of the pieces bordering upon the seam shielded from the hardening process, so that they are not hardened.
