Tecnologia Mecânica

Materials – materials science and engineering fundamentals

The teaching methodology is based on the presentation of the theoretical foundations of each technological process of plastic forming and
welding techniques, as well as their potential or practical implications, consolidated with exercises and laboratory practice.

The Laboratory Component has the following operating conditions:

• Use of a lab coat and appropriate personal protective equipment (PPE) suitable for the activity being carried out;
• Compliance with the mandatory laboratory safety rules.

To acquire knowledge which allow manipulate materials to construct components, equipments and systems by mechanical technology plastic deformation, casting and new additive processes, welding and thermal cutting process.
Generics skills: To provide necessary knowledge about properties and applications of main engineering materials. Specific skills: To know principles of physics, operational features and practical applications of the forming processes by plastic deformation or by casting. Welding process and thermal cutting principles and mechanisms, identification, selection and control. To identify the different welding defects and
inherent repair methods

 Materials properties. Plastic deformation mechanisms. Rolling mill, extrusion, drawing and deep drawing processes. Casting systems.

Additive manufacturing processes.

Welding technology – definitions. Welding machines. Electric arc welding process (MIG/MAG, TIG, SAW, SER and special processes)

Assessment in this course unit may be carried out through continuous (periodic) assessment or by a final examination. The final grade reflects a weighting of 50% for mastery of theoretical content and 50% for understanding and application of the practical content taught in classes.

The first midterm test takes place halfway through the semester and covers the content effectively taught up to that moment, both in theoretical and practical classes.

If the student does not obtain a passing grade through continuous assessment, they automatically move to assessment by final examination. The final examination is held during the periods defined in the academic calendar and covers all the content taught throughout the semester.

Periodic Assessment

Two written tests – PE1 and PE2, with a minimum grade of 8.0 points in each.

PE2 is held on the date of the Regular Examination.

Final Grade (FG):
FG = PE1 (50%) + PE2 (50%)

Pass condition: FG ≥ 10 points

Assessment by Examination (Regular, Resit, Special and Monthly periods)

Written examination (PE) with a minimum grade of 10 points.

Final Grade (FG):
FG = PE
