In this class, joining, mainly welding, will be lectured from the viewpoint of material engineering. The types of welding,
welding materials, phenomena and physical meanings related to welding, defects that occur during welding, and the relationship
between welding and industry will be explained.
The purpose of this class is to understand the importance of welding technology, which is indispensable as an industrial or
structural material, in addition to scientifically understanding joining phenomena through the basics of welding and joining.
- Understanding the types of joints
- Categorizing welding methods and welding materials
- Learning the role and importance of welding in industry
