MTLE-4410

Welding Processes and Metallurgy

Fundamental principles, primary variables, and metallurgical changes associated with both fusion and nonfusion welding processes. Energy sources, rates and modes of energy transfer to the work, and distribution of energy in the work as these affect plastic softening or melting, plastic flow or solidification, post-solidification transformations, heat-affected zone microstructures, residual stresses and distortion, defect formation, and resultant properties; attention to the effects of weldment material, joint design, process, and procedural variables. Physical metallurgy is emphasized throughout. Practical examples highlight theory. Hands-on laboratory exercises complement lectures. Prerequisite: ENGR-2010 or ENGR-1600. Fall term.
