The peculiarities of metal structure of welded joints of structural low-alloy steel after welding using external electromagnetic field were studied. The phase composition, microstructure and microhardness of metal of welded joints produced without and with the use of alternating magnetic fields – longitudinal or transverse were studied. The structural parameters in the metal of the welds and areas of the heat-affected zone were analyzed. The conditions for producing high-quality welded joints during welding of low-alloy steels under the effect of external electromagnetic field, which provide strengthening and crack resistance of the metal, were found. 10 Ref., 1 Tabl., 4 Fig.
Keywords: structural low-alloy steel, welded joints, external electromagnetic effect, alternating magnetic fields, heat-affected zone, phase composition, microstructure, microhardness
