Objetivos

In this Engineering discipline, it is intended that students acquire the theoretical and practical knowledge that guarantees the understanding and framework of manufacturing processes. In order to achieve this objective, students will initially have an awareness in the area of Hygiene, Health and Safety at Work. Then, there will be a framework on the most relevant aspects of dimensional metrology. The third point corresponds to an analysis of the different technological processes of material transformation. At this point, particular emphasis will be placed on Welding Technology. Finally, the Non-Destructive Tests will be analyzed.
It is also intended that students acquire the necessary skills to develop the design of parts produced by welding, according to the specifications normally used in the industry and through the most recent technologies available on the market.

Resultados de aprendizagem e competências

Obtenção de frequência

Theoretical-practical assessment (with a minimum grade of 9,5), through Two Tests (50%), Research Work (28%), Industrialization Project (22%). The minimum grade in each of the two tests is 9,5 values. The recovery of each of the tests can be carried out in the period of Exam Season.



Laboratory evaluation (with a minimum average score of 9,5 values): Reports (35%), Manufacturing Notebooks/prototype (40%) and Laboratory Work Questionnaires (25%). In order to pass the laboratory component, students will have to guarantee the delivery of all laboratory work and a minimum attendance of 80 percent.



IMPORTANT: Failure to meet the delivery dates implies a penalty of 5% of the note for each day of delay.

Fórmula de cálculo da classificação final

CONTINUOUS EVALUATION

Final Classification=Theoretical-practical (50%) + Laboratory (50%)



FINAL EVALUATION

Theoretical-practical (50%) - Minimum grade of 9,5 values

Laboratory evaluation (with a minimum average score of 9,5 values): Reports (35%), Manufacturing Notebooks/prototype (40%) and Laboratory Work Questionnaires (25%). In order to pass the laboratory component, students will have to guarantee the delivery of all laboratory work.

Final Classification=Final exam (50%) + Laboratory (50%)

Avaliação especial (TE, DA, ...)

Students with special statutes must inform the RUC at the beginning of the semester so that a plan for presence/monitoring of laboratory classes can be agreed to allow the application of the UC evaluation rules.

Observações

- Attendance at laboratory activities is mandatory. In case of impossibility to be present, the student must contact the Professor in advance;
- Laboratory work reports are returned to the group for improvement, if they have not reached the minimum classification;
- Students who do not have all their reports approved during the continuous assessment period have the possibility to deliver the reports not accepted by the date of the exams;
- If the student has not obtained the minimum score in one of the tests, he can recover that test on the date defined by the Pedagogical Council for the evaluation on the dates of exams;
- Students who obtain a final mark higher than 17 must submit to an oral exam, otherwise the mark will be 17;
- In written evaluations, only non-programmable scientific calculators can be used.
