WELDENG 4101/7101 – Welding Metallurgy I
This primary core course applies physical metallurgy principles to non-equilibrium thermo-mechanical conditions associated with welding of structural alloys with a focus on carbon steels. The first part of this course introduces the fundamental concepts of welding metallurgy building upon physical metallurgy principles from prerequisite MSE courses or students prior knowledge of metallurgy principles. Topics presented include regions of fusion and solid-state welds, weld solidification, heat-affected zone phenomena, weld defects, and weldability testing. The second part of this course applies these principles to the understanding of the welding metallurgy and weldability of low-carbon, C-Mn, and high strength low alloy steels.
WELDENG 4112/7112 – Weldability
This elective course for undergraduate and graduate students is offered every year in the autumn semester. It presents the basic concepts of weldability, including cracking mechanisms associated with primary fabrication, repair, and service. The course includes both fundamental metallurgical explanation of cracking phenomena and practical examples of weld failures. The following topics are covered:
- Concept of weldability
- Review of welding metallurgy
- Solidification and liquation cracking
- Solid-state cracking
- Hydrogen-assisted cracking
- Fatigue and fracture
- Corrosion
- Failure analysis
- Weldability testing
- Case Studies
The objective of the course is to build upon student’s knowledge of welding metallurgy (WELDENG 4101/7101) to provide an in depth understanding of failure mechanisms in welded construction. Students learn the fundamentals of weld failure mechanisms including those associated with primary fabrication and repair, and those related to service exposure. Remedial measures are also described. Students chose a research topic or case study that they develop into a slide presentation that is presented to the class.
