Abstract
Peculiar features of formation of structure and properties of welded joints of sparsely-alloyed structural steels of the new generation are described. The importance of a careful approach to the selection of materials and processes of their welding to prevent the susceptibility of weld metal and HAZ to brittle fractures. Principal problems of analysing a delayed fracture of welded joints of these steels are considered.
Keywords: sparse alloying, structural steels, welding consumables, cold resistance of metal, fitness-for-purpose, cold resistance of HAZ, delayed fracture, lamellar fracture, research program
