Welding Metallurgy- ME- 513

This course helps students develop an understanding of the main metallurgical principles as they are applied to
fusion welding processes. This course covers Fusion Welding Processes with its particulars such as Heat Flow; Fluid Flow, Metal Evaporation and Chemical Reactions in Welding as well as Residual Stresses, Distortion, and Fatigue. The fusion zone and its affiliated topics is also considered such as Basic Solidification Concepts; Weld Metal Solidification; Grain Structure; Microstructure, Phase Transformations; Weld Metal Chemical Inhomogeneities and Solidification Cracking. The formation of the partially melted zone is also covered; Difficulties Associated with the Partially Melted Zone; The Heat Affected-Zone; Work-Hardened Materials; Precipitation-Hardening Materials: Aluminum and Nickel-Base Alloys.
