Mechanical Technology

Base Knowledge

Materials – materials science and engineering fundamentals.

Teaching Methodologies

Oral presentations and written presentations according to the type of activity and content of the respective classes to be taught (theoretical and practical).

Component II, has as a working condition:

Use of protective gown.

Attention to mandatory safety rules in the laboratory.

Learning Results

Goals: To provide the students with necessary knowledge about principles of physics, operational features and practical applications for each of the welding and forming processes, as casting and working processes, learnt, and how these processes should be selected, controlled and applied to each concrete case, to manipulate materials, especially to metallic materials conformation of, for the mechanical construction of components, equipment and systems; solve theoretical-practical problems in the technological processes presented, resolution to be done mainly in theoretical-practical classes, that may, when necessary, be preceded by corresponding theoretical exposition.

Generic Skills: To know de proprieties and applications ways of engineering materials.

Specific Skills: To understand the mechanisms that are part of the forming mechanical technology processes, know how these processes should be selected, controlled and applied in each specific situation.  To understand the mechanisms that are part of the welding processes, thermal cutting and mechanical technology, know how these processes should be selected, controlled and applied in each specific situation in the material joints; to diagnose defects in welding processes and thermal cutting; to define all of the procedures to ensure necessary safety conditions and correct welding work methods; to identify the different welding defects and suggest methods to solve these.
