Features of metal structure in 09g2S steel welded joints were studied in welding with application of a longitudinal external electromagnetic field. The influence of field frequency (f = 2; 12; 50 hz) on phase composition, microstructure and microhardness of welded joint metal was studied. It was found that significant changes of structural parameters in the weld metal and in the subzones of the heat-affected zone (HAZ) take place in the studied frequency range. The influence of frequency of electromagnetic effect in low-alloyed steel welding is more pronounced in the metal of the weld and HAZ in the overheated subzone (coarse grain). application of f = 12 hz ensured a uniform microhardness level both in the weld metal and in the haZ subzones, as well as grain structure refinement in the overheated subzone (Ð? HAZ) of 09G2S steel welded joint. [ABSTRACT FROM AUTHOR] |
