Fundamentals of welding science and technology

Fundamentals of Welding Science and Technology is a foundational course that introduces the scientific principles and technological practices governing modern welding processes. The course explains the physics of heat generation and transfer, melting and solidification behavior, and metallurgical transformations that occur during welding. Emphasis is placed on understanding weld pool dynamics, microstructural evolution, and the relationship between welding parameters and joint performance.

Participants gain exposure to major welding processes such as arc welding, resistance welding, and solid-state welding, along with the role of consumables, shielding methods, and power sources. The course also covers weld defects, residual stresses, distortion, and basic weld quality control techniques. By integrating materials science with process technology, this course builds a strong conceptual base for selecting, designing, and optimizing welding procedures in industrial and research applications.
