Abstract: Abstract The purpose of this work was to study the issues of ensuring the standard quality indicators of installation of welded pipes of field pipelines with a deposited layer of high-chromium steel. The research was performed on pipes made of steel 09G2S of the K48 strength category with a diameter of 258 mm and a wall thickness of 6 mm. The formation of the deposited layer on the inner surface of the pipe ends was performed by electric arc welding in protective gases with a wire SV-12X13 with a diameter of 1.2 mm. Welding of ring joints of pi...
