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--based and Ni-based alloys, and 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 the final welding microstructure and performance using physical metallurgy and heat transfer knowledge.
  • Can create a limited test plan to evaluate the influence of welding process parameters on the joints’ characteristics.

General competence:

After passing the course, the candidate:

  • Can describe different common welding terms and codes based on the common standards.
  • Can analyze information from WPS.
  • Can analyze characteristics and challenges of welding processes for different metallic materials.

Learning methods and activities

  • Lectures
  • Videos
  • Lab and lab exercises.
  • Text/textbooks/slides

Compulsory assignments

  • Assignments
  • Oral presentation
  • Mandatory attendance in the laboratories

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.
