MS3606 Introduction to Welding and Joining Metallurgy

Welding and joining are presented from the point of view of metallurgy. Topics include the nature and applications of welding and joining processes; the welding thermal cycle; metallurgical effects of the welding thermal cycle; welding and joining of steels, aluminum alloys, stainless steels and heat-resistant alloys. Also, weldment inspection and quality assurance are introduced.

Course Learning Outcomes

At the completion of the course students will be able to:

• Know the basic vocabulary of welding and welding metallurgy, especially for fusion welding processes.
• Explain the advantages and limitations of the more common welding processes.
• Calculate heat flow in fusion welding and explain the effect of the welding thermal cycle in welded materials.
• Understand gas-metal interactions and their implications in fusion welding.
• Understand the effect of solidification processes on microstructures in various regions of a weldment.
• Describe the relative weldability for ferrous, titanium, and aluminum alloys.
• Apply the physical metallurgy principles which were presented in MS2201 and further developed in MS3202.
