摘要
A method of connecting together two unit elements (2, 4) of an undersea fluid transport pipe that is subjected to fatigue, by welding together two metallic or bi-metallic unit pipe elements that have been put into abutment via their respective free ends (2a, 4a), the welding being done by making three distinct weld beads (6, 8, 10), with a last weld bead (8) being deposited between two lateral first weld beads (6, 10), and being followed directly by controlled sanding of the weld beads in order to apply compression stresses on them.
