Abstract

Underwater butt welding method as in 7104071, but in which two horizontal coaxial aligned pipe lengths are connected by welding a bottom underlay strip to the bottom part of the outer pipe walls, and a top underlay strip to the top part of the inner wall of the pipes so that only part of the circumference is covered by the strips. The space between the pipe lengths is filled with welding material along the distance over which both overlay strips stretch. The ends of the welds against the inner wall and adjoining the top underlay strip are ground away so that an overlap is created with the bottom underlay strip, after which the remaining gap between both pipes is filled with welding material.
