Learning outcome

Knowledge:

After passing the course, the candidate must have knowledge of:

  • Different welding, joining and direct energy deposition additive manufacturing processes
  • Welding performance of steels, stainless steels, Al-alloys, Ni-based alloys, Ti-based alloys based on their physical metallurgy
  • Welding procedure specification development based on welding standards and codes
  • Weld monitoring, non-destructive testing, and mechanical testing.

Skills:

After passing the course, the candidate:

  • Can correlate the process parameter to final welding microstructure and performance using physical metallurgy and heat transfer knowledge.
  • Can create limited test plan to evaluate the influence welding process parameters on the joints’ characteristics.

Further on evaluation

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.

The portfolio assessment includes lab exercises, presentations, evaluation of other groups and a project. All elements are linked to a project, with various joining/welding applications, which are specified when starting the course. Here, students are expected to participate actively, also in groups, to reflect on their own work as well as other group projects and presentations.

The project will include various joining technologies, metals, standards, procedures and applications - with assessments of mechanical and structural performance in relation to given requirements. The students will also carry out practical experiments and become familiar with the impact process parameters have on process and welding quality. This is linked to the project in portfolio assessment, where a report must also be written with an associated presentation and assessment/self-assessment.

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.

In the case of a continuation exam, the form of the exam can be changed from written to oral.
