Abstract
A study of the morphology of the metal structure in the near-seam section of the heat-affected zone (HAZ) is performed by simulating pipe manufacture. The influence of microstructure on HAZ metal resistance to brittle fracture is estimated. Causes for low values of the impact toughness of the HAZ metal are revealed as well as the possibility of improvement by carrying out post-welded metal local heat treatment.
