Further on evaluation
(the information may be changed until June 15th)
Portfolio assessment and the final written exam are the basis for the grade in the course. The grade is divided into 30% for portfolio assessment and 70% for the final exam.
Mandatory work requirements to gain admission to the exam are:
-Assignments
-Oral presentation
-Mandatory attendance in the laboratories
The portfolio assessment includes a lab report, a final project report, a report on the evaluation of other group projects. All elements are linked to a project, with various joining/welding applications, which are specified when starting the course. The project can be carried out in a group of 2-3 students, and it should contain a detailed description of the participants' individual contributions. The portfolio will include various activities related to mechanical and structural performance in relation to the given requirements of welded samples. The students will also carry out practical experiments and become familiar with the impact of process parameters on process and welding quality.
If there is a re-sit examination, the examination form may be changed from written to oral. There will be a re-sit exam in May/June and August. Students can only attend one of the re-sit exams.
