Abstract

PURPOSE:To improve efficiency of operation to a great extent, by applying cementation simultaneously with heating in a furnace for soldering by a means for prefixing soldering end metals to both sides open ends of a steel pipe. CONSTITUTION:End metals 12, having respectively contact surfaces 13 curved outwards or inwards and having at the back a coupling portion 14, are fitted and fixed to both sides open end portions of a steel pipe 11 having a relatively small diameter not greater than about 25mm and applied with a layer of copper plating P for protecting the pipe from cementation at least over the entire outer surface, after coating a plating layer or soldering material to the surface of end metals 12. In this state, cementing process is applied simultaneously to the surface of end metals 12 by heating the same in an atmosphere of cementing gas in a furnace and thereby soldering the coupling portions 14. Then, the curved contact surfaces 13 of end metals 12 are hardened by way of quenching. Thus, it is enabled to improve the quality of push rods and to improve efficiency of operation to a great extent.
