Abstract
In order to assess the integrity of welded pressure vessel containing a crack, the behavior of three-point bending specimens made of HSLA steel welded joint are tested at -40°C, and their fracture behaviour analyzed, as a conservative measure of crack resistance. Specimens were made of low-alloyed steel NIONIKRAL 70, welded by SAW process. Surface notches were machined by the electro-erosion method in the parent metal (PM), heat affected zone (HAZ) and weld metal (WM). The highest resistance to cracking was in PM, and the lowest one in WM, due to so-called pop-in behaviour.
