Arc welding of annular seams under flux in high-strength X80 steel pipe

Steel in Translation Aims and scope

Abstract

The relation between the content of martensitic-austenitic phase and the final temperature in accelerated cooling is investigated, in terms of the attainment of high deformability without failure. The ratio of the yield point to the strength (Y/T) in the longitudinal direction (L) of X80 steel pipe produced by UOE technology is found to be between 0.74–0.79. This indicates good deformability of the pipe. A welding technology has been developed such that the metal in the seam matches the strength of the X80 steel pipe. In industrial flexure tests, when the internal pressure is 72% of the standard yield point (SMYS) of X80 steel, the failure of X80 steel pipe welded by the given technology occurs in the basic metal, far from the annular weld.
