Analysis and Modeling of Welding

Analysis and Modeling of Welding focuses on the scientific and computational approaches used to understand, predict, and optimize welding processes. The course introduces the fundamentals of welding physics, including heat transfer, fluid flow in the molten pool, metallurgical transformations, and residual stress and distortion development. Emphasis is placed on developing analytical and numerical models that describe the complex thermal–mechanical–metallurgical interactions occurring during welding.

The course covers analytical heat source models, temperature field prediction, cooling rate estimation, and their influence on microstructure and mechanical properties. It also introduces numerical techniques such as finite element and finite difference methods for simulating welding processes, residual stresses, and deformation. By integrating theoretical concepts with practical modeling approaches and industrial case studies, the course equips participants with the skills required to analyze welding behavior, improve joint design, and support process optimization and quality assurance in advanced manufacturing applications.
