abstract: To provide serviceability of joints of pipelines produced using flash butt welding (FBW) alongside with the condition of strength the requirement to impact toughness KCV is set forth.Its level is established according to the requirements to the joints produced using arc welding methods, for which the probability of appearance of crack-like defects in them is peculiar.Absence of even preconditions to formation of cracks in the FB-welded joints allows initiating the review of requirements to impac
