Tecnologias de Ligação de Materiais

Objectives

This course aims to provide the student with knowledge and skills in the area of materials joining processes. To achieve this goal, it is necessary that the student understands the theory associated with the fusion welding processes, solid state welding processes, brazing and soldering and adhesive bonding. Specific processes for metallic and non-metallic materials are also addressed. The weldability of different materials and the quality control of the obtained joints are analysed. At the end of the course the student should be able to select the most suitable joining process(es) for a given application and to develop the specific procedure to be applied for that case.
