| Learning Outcomes |
At the end of this course, the students;
- Classify engineering materials; explain their basic structures, properties, and applications.
- Describe atomic structure, crystal structures of metals, crystal defects, and phase diagrams.
- Explain the thermodynamic, thermal, and metallurgical processes occurring during welding; interpret concepts such as heat transfer, phase transformations, and the Heat-Affected Zone (HAZ).
- Analyze phase transformations, microstructural changes, and the effects of thermal cycles during welding of different materials.
- Evaluate the causes of welding defects, residual stresses, cracking, distortions, and microstructural changes that may occur during the welding process, and develop preventive strategies to minimize these effects.
