Learning outcomes of the course unit

Students will acquire knowledge of unconventional types of modern welding technologies, and will be able to apply these technologies to particular examples of special welding. They will be able to independently and creatively work on a welding procedure.

Prerequisites

Students are expected to be familiar with the fundamentals of fusion and pressure welding technology, as well as with science of materials.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

Course-unit credit is awarded on condition of having delivered written reports from exercises, and worked out the assigned reports during the semester. Examination: the exam has a written and an oral part and tests student´s knowledge acquired in the lectures and exercises.
