Course content

Lectures emphasize that students learn complex design, manufacturing techniques and quality control methodologies for welded structures. In this context, they learn about the types of non-integrity and defects of welded joints by destructive and non-destructive methods (NDT). After completing the courses, students should know how to prepare and approve the qualifications of welders, welding operators and welding supervisors. In this context, they should be able to prepare welding process procedures (WPS) and how to obtain certified welding procedures (WPQR). Students should know the issues of occupational safety compliance in welding by different methods. At the same time, students should be able to better assess the influence of operational stresses that cause degradation of the operational reliability and durability of welded joints produced in the construction of welded structures. Lecture Outline: 1. The relationship between design, material and weldment fabrication 2. Weld terminology 3. Types of welds and their stresses 4. Causes of degradation of weld joint properties 5. Internal stresses and deformations in the welded structure (hereinafter referred to as SK) 6. Weldability of steels, structural weldability, suitable welding methods for SK 7. Basic structural types, influences on SK design 8. Weld types, weld bevels 9.Weld quality grades according to EN ISO 5817 10. Weld marking on drawings according to EN ISO 2553, EN ISO 4063 11. Selection of steels and additional materials for the production of SK, their marking according to EN 499, EN ISO 14175 and EN 10027 12. Principles of design of statically stressed SK Design principles for dynamically stressed SK 14. Calculation of welded joints of machine structures according to ČSN 05 0120 15. Design of steel structures according to ČSN 731401 and DIN 18800 16. Principles of design of SKs made of aluminium alloys
