Course Goals / Objectives:
First part of the course introduces the fundamental concepts of welding/joining metallurgy. This will build upon physical metallurgy principles from prerequisite MSE courses
Topics presented include regions of fusion and solid-state welds, weld solidification, HAZ phenomena, weld defects, and weldability testing
This course provides the foundation for the second part of the class, as well as, subsequent required and elective courses to be offered in related welding/joining metallurgy courses
This second part of the course will provide basic understanding of the nature of iron and its allotropic form. In addition, the effect of alloying elements on the solid state transformation of iron alloys (steels) will be discussed
Heat treatment of carbon and low-alloy steels is discussed and related to the effect of welding thermal cycles on resulting structure and properties of steels in the heat-affected-zone and weld metal
in the third part of the course, welding procedures, steel and filler metal classification systems, and post-weld heat treatments are described. Weldability and weldability testing are discussed
Major emphasis is placed on the toughness characteristics of steel weldments and the influence of hydrogen in producing HAZ and weld metal cracks
