METHOD FOR MACHINING METAL CONDUITS TO FORM A V-SHAPED PROFILED SECTION ON PIPELINE METAL PIPES; METAL CONDUIT; WELDING METHOD COMBINING IN A COMMON LASER FUSION BATH AND ELECTRICARC FOR ASSEMBLING SAID CONDUITS

摘要

the invention relates to a process for machining the ends of a pipe(1) in order to form the metal when placed end to end witha pipe type led the same to form the pipeline.the plan of joint (3) with a groove in a drive as.the invention consists in that the ends of the leads are cut andthe profile of each end has at least one first sectionright, on the inside, intended to be part of the heel ofin section v, and a root circle connecting the straight sectionthe profile of a straight section (5) inclined with respect to the section.the right of the profile at the outer edge of the tubular part. l ~ applicationwith metal pipes, in particular for pipelines.
