Objectives

The objectives in this curricular unit (UC) are:

• Follow the programme planned for each week;


• Participate in the questions and problems presented to the students in the classroom;


• Get in contact with the several welding processes presented in practical classes;


• Elaborate a monography and respective presentation in the classroom (in group work environment) on a topic related to the programme;


• Elaborate a report and respective presentation in the classroom (in group work environment) on a topic given in practical classes (PL).

Learning outcomes and competences

The learning outcomes are settled on top of the technical-scientific knowledge acquired in other curricular units in Materials Science and Engineering. They exhibit a reinforcing and consolidative spirit, designed to attend the needs of the materials joining related industry, particularly welding. The outcomes are:

• Acquaintance with the more industrially relevant joining processes, their working principles, and their operation;

• Adequate selection and parametrization of the joining processes for different types of joints and for the metallic alloys suitable for welding;

• Identification and resolution of the main metallurgical defects/problems in welding engineering;

• Acquaintance with the normative references and documentation relative to planning, supervision and quality control of welded joint in industrial environment.

Teaching methods and learning activities

The PL will have a strong practical nature, with small periods of oral exposition and demonstration activities. In such classes each student will be required to perform welding operations using the processes previously lectured in TP classes, and to implement a metallurgical analysis of the welded joints.

Eligibility for exams

Eligibility is met by cumulatively:

• be eligible to both UC components (TP + PL);
• do not miss PL classes above the maximum limit;
• obtain a minimun exam grade of 8 (rounded to unit).

Calculation formula of final grade

The final grade is given according to the following formula:

CF = 0.50 NE + 0.35 NP + 0.15 NM

CF - Final grade
NE - Written exam
NP - PL classes report
NM - TP classes monography

Special assessment (TE, DA, ...)

Special assessment follows the same approach and calculation formula of normal assessment.

Classification improvement

Classification improvement to TP component is achieved through written exam. Classification improvement to PL component requires attending classes and completing the assignments proposed in the following curricular year.
