Course description and aims
A junction is when a binding force emerges between two parts through a joint interface. Some type of energy is used to create the binding force, and results in organization forming at the joint interface. Because the making of organization influences its reliability, security, durability, thermal resistance, and corrosion resistance as a machine, the instructor integrates modern junction techniques and products into the lecture. The instructor then covers adhesive bonding technology that is growing in importance. Specifically students learn about surface processing, selection of adhesives, mechanical design of joints, evaluation and assurance of durability, and content related to joining equipment systems, thereby learning knowledge of adhesive bonding technologies necessary for a mechanical engineer.
Student learning outcomes
Joining parts is essential for the manufacturing of industrial products. In this course, we will start by showing the big picture of joints engineering. Students will acquire general knowledge related to welding, and brazing and soldering. We will then cover glued connection technology that is of increasing importance in recent years. Students will specifically learn about surface treatment, adhesive selection, mechanical design of joints, evaluation and assurance of durability, and joining equipment systems. Students will also acquire knowledge on glued connections technology needed for mechanical engineers.
Students will gain the following knowledge by taking this course.
1. Be able to classify energy sources used for joining, and the advantages of those energy sources.
2. Understand organizational formation of joint interfaces for welding, brazing and soldering, diffusion bonding, and friction bonding, and be able to logically explain joining techniques for products.
3. Be able to explain reliability, security, durability, heat-resistance, and corrosion resistance from the interface organization state.
4. Acquire skills for surface treatment, the selection of adhesives, the mechanical design of joints, and the evaluation of durability.
