Abstract
PURPOSE:To improve soundness of a surface treated layer of a cylindrical body and to shorten the welding time by providing a short surface treatment unformed part to the surface treated cylindrical body to perform high density energy welding and setting its heat gain to a specific value. CONSTITUTION:At the time of welding a long-size cylindrical body 13 to be joined to a cylindrical body (pad part) 12 on which the nonoverheat resistant surface treated layer 14 is formed on the same axis, the short surface treatment unformed part 15 is set on the cylindrical body 13. Further, high energy electron beam welding is applied as a welding means and a joint part 15 of the pad part 12 is welded to the cylindrical body main body part 13 by an electron beam welding machine 16. At this time, the welding heat gain is set so that the generated heat stress on the surface treated layer 14 is made to under the rapture stress. By this method, the surface treated layer 14 is prevented from being damaged and its soundness is improved. Since the surface treatment unformed part can be reduced, the total welding time is shortened.
