Abstract The studies’ results of the high-speed electrothermal treatment effect on the structure and hardness of various zones of welded joints made of low-alloy structural steel 10ХСНД (10KhSND) are presented. It is shown that carrying out high-speed electrothermal treatment at 950–980 °C leads to the formation of a homogeneous, fine-grained ferrite-perlite microstructure with practically unchanged hardness values in all zones of the welded joint except for the weld root, where slightly higher values of microhardness are registered.
Keywords welded joint, low-alloy structural steel, high-speed electrothermal treatment, structure
