W13: Practical Welding Metallurgy

Introduction to basic metallurgy concepts with practical applications of material properties from time of manufacturing through to welding fabrication. We will discuss crystal structures, grain size, effects of welding and how these change the mechanical properties of our engineering alloys. By understanding fundamental physical metallurgy concepts, we will evaluate scenarios of how and why we use preheat, PWHT, or place limitations on heat input. Our emphasis on this course will be carbon and low-alloy steels but introduce stainless and non-ferrous alloys for future more specialized study.
