Learning outcomes

Knowledge and understanding The student must, after completing the course, be able to show knowledge of:

• physical and welding metallurgy of different metal alloys, including dissimilar alloy combinations.
• quality aspects related to imperfections, and discontinuities in welding and additive manufacturing, incluiding cracking mechanisms.
• residual stresses and distortion phenomena in welding and additive manufacturing processes.
• basics of computational thermodynamic tools for prediction of phase formation and phase transformation.

Competence and skills The student must, after completing the course, be able to:

• connect the particularities of welding and additive manufacturing processes and their associated thermal cycles to the resulting microstructure in a range of metal alloys.
• correlate specific microstructural features with cracking susceptibility, mechanical and/or corrosion properties in a range of welded/additively manufactured alloys.
• propose and formulate ways to avoid imperfections, defects and failures of welded and additively manufactured deposits.

Judgment and approach The student must, after completing the course, be able to:

• show awareness of sustainability in welded and additively manufactured material in relation to quality aspects.

Course contents

This course gives insights into the metallurgy of welding and additively manufactured deposits of different metal alloys widely used in the industry. The influence of the thermal cycles involved in the welding and additive manufacturing processes on the microstructure and properties of metal alloys is studied. In addition, the course covers several aspects connected to welding metallurgy: quality, residual stresses, fatigue, and some initiation to computational thermodynamics to predict microstructure. It is expected that the students combine the previous knowledge acquired in the courses: Advanced Materials Science, Welding Processes and Additive Manufacturing processes with the contents of this course. This course is designed and developed in cooperation with industries, therefore, industrial guest lecturers and study visits complement this course. The previous knowledge of the students on materials science is essential.
