The thermal effects from welding and heat treatment influence the microstructure and mechanical properties of welds. Various materials, such as carbon steels and other alloy grades, are affected by heat treatment which changes the weld metallurgy and influences the final welded product. Better understanding of the impact of welding and heat treatment practices can allow for the weld quality and reliability to be optimized for the application.
