Abstract

Parameters of heat-affected zone (HAZ) effect on microstructure, phase composition, and microhardness of welded joints (WJ) metal of 09G2S steel, obtained without and with the use of longitudinal and transverse electromagnetic fields, are studied. Changes in the structural parameters of the weld metal and the heat affected zone in the areas of overheating, normalization, etc. were analyzed. The conditions for obtaining high-quality crack resistant welded joints under the influence of an external electromagnetic field were determined.
