Enable the understanding of the fundamentals of thermal processing of materials applied to metal casting and welding technologies.
Present the main casting and welding processes with emphasis on the operating parameters, economic aspects and final quality of the components.
Develop the ability to select casting and welding processes, choose the respective operating parameters and project and design the respective molds and tools.
1 Introduction to thermal processing technologies.
2 Fundamentals of thermal processing of materials applied to metal casting. Fundamentals of fluid flow in liquid metals. Heat transfer applied to metal casting. Thermal strains and stresses.
3 Fusion, pouring, solidification and cooling of metals in metal casting. Heating and melting of metals. Solidification and cooling shrinkage. Metallurgical properties.
4 Permanent and non-permanent mold. Gravity and pressure casting. Heat transfer in conductive and insulating mold. Engineering analysis of mold filling and riser design.
5 Fundamentals of thermal processing of materials applied to welding. Welding heat sources, energy density and heat input. Analysis of heat flow during welding. Solidification and metallurgical properties.
6 Electric arc, resistance and high energy density (laser and electron beam) welding processes. Solid-state welding: friction and diffusion.
7 Quality, inspection, design and costs.
Teaching methodologies are design to support the acquisition of theoretical knowledge with problem solving and laboratory tests. The experimental work reinforces the applicability to real manufacturing processes as well as the autonomous work and accountability of the students. The evaluation methodology in this course is the following: 1 exam (60% of the final classification) and 1 group project comprehending the definition of operating parameters and the
design of the molds and tools to fabricate a metallic component through thermal processing technologies (30% of the final classification) and laboratory questions (10% of the final classification).
