Abstract
Peculiarities of formation of high quality flash-butt welded joints on pipes are analyzed. Factors affecting the results of impact tests of standard specimens are considered. Toughness properties of metal in the welding zone have been studied by using different impact test methods. It is shown that metal of as-welded joint made at optimum parameters has sufficiently high resistance to impact loads. Conditions for performing flash-butt welding and inspection of the joints providing high operating reliability of pipelines have been determined.
