Information × Registration Number 0122U002215, ( 0225U001930  ) R & D request Title Investigation of the influence of arc welding, high-frequency mechanical forging and operating conditions on the physical and mechanical properties of welded joints of bridge steels and special purpose steels with yield strengths of 350 and 1200 MPa Head Pozniakov Valerii D., Доктор технічних наук Registration Date 04-04-2022 Organization E.O. Paton Electric Welding Institute (PWI) popup.description1 To establish the effect of arc welding, high-frequency mechanical forging, static and cyclic loads on the resistance of welded joints of bridge steels with σ0.2 ≥ 350 MPa and special purpose steels with σ0.2 ≥ 1200 MPa brittle fracture and crack formation fatigue and develop to improve their service properties in the manufacture of responsible metal structures for civil and military purposes. popup.nrat_date 2024-12-09 Close
