Abstract
Requirements to circumferential welded joints in large-diameter pipelines are considered. Results of experimental studies of strength and deformability of flash butt welded joints on standard and large-scale specimens are generalised. It is shown that development of a test procedure and requirements for toughness of the weld metal, allowing for specific peculiarities of formation of the flash butt welded joints, is required to control fitness for purpose of the joints.
Keywords: flash butt welding, pipeline, welded joint, defects, performance, test criteria, large-scale specimens, require¬ments to properties, fitness for purpose
