The results of investigation of the reasons for the formation of cracks in welded joints in 20  K steel are presented. The nature of failure was determined by the methods of vacuum thermal etching in metallographic and fractographic studies of fracture surfaces. The intragranular nature of failure by the ‘cold cracking’ mechanism is described. © 2015 Taylor & Francis. Source

The composition of a new general-purpose ceramic flux for welding of carbon steels is described. The flux is not susceptible to hydration, has low chemical activity in relation to deposited metal ensuring minimum oxidation of the alloying elements, with easy separation of the slag layer immediately after welding. Consequently, no labour-consuming operations are required for the removal of the slag from the surface of the welded joint. The flux ensures efficient melting with the edges of the welded components and prevents the formation of unacceptable defects in the weld metal. © 2012 Copyright Taylor and Francis Group, LLC.

Investigations were carried out into the properties of sheets and forged 03Kh16N9M2 austenitic steel and the properties of welded joints in equipment working in a wide temperature range from –196 to 600°C. The determination of the mechanical properties of steel and of welded joints and also of cyclic strength characteristics shows that the properties of these steels are higher in a wide temperature range than the properties of 12Cr18Ni10Ti steel. A method was developed for welding bodies of cryogenic equipment with large thicknesses of welded joints with no need for heat treatment. © 2015, © 2015 Taylor & Francis. Source

The technology of automatic narrow-gap argon-arc welding of pipes of the main circulation pipeline Du-850 of water-water nuclear reactors is investigated and developed. Welding is carried out using automatic welding systems with Sv-10G1SN1MA welding wire. The welded joints were investigated by metallographic methods, and the mechanical properties were determined. © 2014 © 2014 Taylor & Francis. Source
