The report describes the results of research on the effect of specific to arc welding thermal cycles on the structure, mechanical properties and resistance to fatigue and brittle fracture of welded joints of high-strength structural steels with yield stress of 350-800 MPa. The results of practical application of welding technologies developed on the basis of such research in manufacture or repair of vehicles, machinery and engineering structures of long life are presented.
