Welding Metallurgy of Iron-based Alloys, 6 Higher education credits

Svetsmetallurgi av järnbaserade legeringar, 6 Högskolepoäng

Established: 2023-02-02

Established by: Department of Engineering Science

Applies from: H23

Learning outcomes

Knowledge and understanding

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

• metallurgy and welding metallurgy of different iron-based alloys such as carbon steel and cast iron
• manufacturing aspects and standardised classification of steels
• heat treatment routines related to welding and their effect on the properties of the material
• quality aspects related to defects and discontinuities within welding, including cracking, fracture mechanisms, and corrosion

Competence and skills

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

• connect welding and its corresponding thermal cycles to the resulting microstructure of different iron-based alloys such as steels and cast irons
• correlate specific microstructural properties with cracking susceptibility, mechanical and/or corrosion properties of welded material
• propose and formulate ways to avoid imperfections, defects, and failures in welded components

Judgement and approach

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

• show awareness of sustainability in welded material and how quality aspects in welding relate to economic and environmental sustainability

Entry requirements

Bachelor of Science in Mechanical Engineering, Manufacturing Engineering, Materials Engineering, Marine Engineering, Welding Engineering or equivalent. Additionally, the Bachelor of Science degree must be comprised of a minimum 15 HE credits in mathematics. English course 6 in the Swedish upper secondary school or equivalent.

The forms of assessment of student performance

Individual written examination. Individual written assignment. Groupwise laboratory work with individual written report.

Course contents

This course covers the welding metallurgy of steels and cast irons that are commonly used in the industry by first proving an overview of related manufacturing processes to understand the connection to the material's properties and their influence on the welding process. How thermal cycles, present during welding, change the microstructure and properties of welded material are treated. Furthermore, the course covers various aspects related to welding metallurgy such as quality, defects, and corrosion properties, as well as different mechanical failure mechanisms.

Other regulations

Course grading: F/Fx/E/D/C/B/A - Insufficient, Insufficient- more work required before the credit can be awarded, Sufficient, Satisfactory, Good, Very Good, Excellent

Course language: The teaching is conducted in English.
