ENGG955: Literature Planner and Summary on Dissimilar Metal Welding

This document presents a literature planner and summary focusing on the research of dissimilar metal welding. It includes detailed analyses of seven research papers, each addressing specific research questions related to the challenges and considerations in welding dissimilar metals, such as creep-resistant steel and stainless steel. The literature review explores various aspects including the mechanical behavior of welded joints, process control, and the impact of welding parameters. Key themes discussed involve the formation of intermetallic compounds, carbon migration, and the influence of filler metals on the final microstructure and mechanical properties. The findings from these papers highlight the importance of selecting appropriate filler metals, understanding the effects of post-weld heat treatment, and addressing potential gaps such as the formation of carbide depletion zones. This planner also examines the application of dissimilar metal welding in high-temperature furnace applications and nuclear reactors, emphasizing the need for robust welding procedures to ensure long-term performance and reliability. The summary concludes with a discussion on residual stress and its effects on the overall performance of welds, underscoring the critical need for careful consideration of welding parameters and the resulting stress states.
