FIELD: mechanical engineering. SUBSTANCE: method involves effectuating local rewelding over the whole section of welded joint at the area spaced from crack end by a distance of 2-5 thicknesses of weldable material to wards crack; effectuating rewelding of welded joint at the area adjacent to other end of crack at a distance of 1-3 thicknesses of weldable material from other end of crack; conducting rewelding until complete connection with previous rewelded area with overlapping is provided. EFFECT: high quality of welded joints and enhanced reliability in operation. 1 dwg
