The heat-affected zone (HAZ) of the weld joint of low-carbon microalloyed steel has a complex microstructural configuration. The microhardness and microstructure of industrial samples of a 150-mm welded joint of ABS EH36 Z35 offshore steel heavy plates after the normalizing process and additional post-weld heat treatment (PWHT) were investigated. This paper presents the positive effect of the post-weld heat treatment on the decreasing of local microhardness and the increasing of the low-temperature resistance to brittle fracture of the grain-coarsened HAZ of the tested type of the welded joint.
