摘要
A method of making undersea steel pipes, by assembling unit pipe elements together end-to-end by welding, the steel or metal alloy weld beads of said welds being disposed on the outside of the pipe, wherein localized peening is performed on the inside of the pipe to increase the compression of the steel or metal in the vicinity of the welds and over the adjacent peripheral inside surface of the pipe on either side of the weld so as to create a swath of surface that has been peened over a limited distance L in the axial longitudinal direction of said pipe. The peening is preferably performed using a wheeled carriage fitted with a peening tool.
