| Abstract Scope |
Dissimilar metal welds (DMWs) are used in nearly every industrial sector, from power and aerospace to automotive and chemical processing. Despite their widespread use, DMWs often the most common point of failure in industrial systems. In this work, we present an innovative approach – solid-state additively manufactured transition joint (SAM+J) – to significantly improve the creep and thermal cyclic performance of DMW for high-temperature services. We will cover the overall design and engineering concept of SAM+J, the use of integrated computational weld engineering (ICWE) modeling tool to guide the design and optimization of SAM+J. Examples are given for SAM+J between Grade 91 ferritic steel and SS304 stainless steel, through a combination of ICWE simulations and creep testing experiments, where SAM+J eliminates the weakest links – the weld and HAZ region – in DMW, and the failure location shifted to the base material of Grade 91 steel. |
