Phase transformations in specimens of low-alloy pipe steels subjected to a treatment corresponding to the heat cycle of welding are studied using a high-speed dilatometer. Thermokinetic diagrams simulating the transformations in characteristic regions of the heat-affected zone are plotted. The results are compared to the properties of longitudinal welds of large-diameter pipes. © 2012 Springer Science + Business Media, Inc.
