Hydrogen and Preheat Management in Welded High Strength Steel for Defense Applications.
Abstract
With the need for new approaches to improve hydrogen management in higher strength steels, three tasks, each with its special focus and potential contributions, were established to promote cooperative research with TTCP operating assignment 013. These efforts are timely due to the introduction of even higher strength steels in Naval structures and defense hardware. These steels use new concepts of strengthening (i.e. precipitation) and not just the traditional eutectoidal decomposition. As the strength level increases the amount of allowable diffusible hydrogen content decreases and has decreased to a level of the uncertainty in the practice of diffusible hydrogen measurement. At these lower hydrogen levels, the hydrogen distribution is as important as the average weld metal diffusible hydrogen content.
