Abstract Scope |
Welding procedure qualification could be streamlined if physical simulation methods could be applied to predict maximum heat input limits for welding of S-1 steels with toughness requirements for naval ship building applications. While thermomechanical physical simulations have been used for decades, comparatively few works directly compare Charpy Vee Notch (CVN) impact toughness properties in physically simulated samples to actual weld heat affected zone toughness results. The goal of this work is to develop a physical simulation method that can provide quantitative agreement in microstructure, microhardness, and CVN impact toughness between simulated HAZ and actual weld specimens. A closed-loop validation approach will be presented and differences between simulated and real weld HAZ specimens will be discussed using two S-1 shipbuilding steels, DH-36 and HSLA-65. |
