Learning Assessment
Learning Assessment Procedures
The exam consists of an oral test. During the lessons, application exercises of the course contents are carried out in the laboratory aimed at learning practical experimentation by the students. The laboratory exercises, each described in the form of a technical report, and the topics covered during the lectures are discussed during the oral exam. The evaluation during the oral interview will be based on: knowledge of the topics covered, the relevance of the answers to the questions asked, the ownership of technical language, the ability to make connections between the contents of the program.
To guarantee equal opportunities and in compliance with current laws, interested students can request a personal interview in order to plan any compensatory and/or dispensatory measures, based on the educational objectives and specific needs. You can also contact the CInAP (Centre for Active and Participated Integration - Services for Disabilities and/or DSA) professor of your Department.
Examples of frequently asked questions and / or exercises
- Describe the defects found in electrical resistance weldings and the most common NDT methods for revealing them.
- How is mutual induction used in eddy current inspection?
- What does pulsed thermography mean?
- Describe the phenomenon of Attenuation in Acoustic Emission test and the three main causes that determine it. Why it is important to know the level of attenuation during a non-destructive test.
- What is the geometric penumbra in radiographic testing? How is it calculated?
