Design, production and quality assurance of the weld seam
Main focus
- Welding-compliant design in practice (production and load-compliant) for static and dynamic loads
- Control the quality of a welded construction as early as the development stage
- Avoiding cases of damage and optimize welded constructions
- Creation of standard-compliant welding drawings according to ISO 2553 with sensible tolerancing according to ISO 13920 and ISO 9013, definition of the required evaluation group according to ISO 5817 - steel (ISO 10042 - aluminum alloys)
On the subject
Welded joints play an important role in mechanical engineering, plant construction, rail vehicle construction, pressure vessel construction, vehicle construction and many other industries. It is therefore essential for designers and engineers to have extensive knowledge of the design of welded constructions and their quality control. To ensure the weldability (= joinability) of an assembly, the structural design (including dimensioning), the weldability of the selected materials and the manufacturing options (e.g. accessibility) should always be taken into consideration. Standards such as ISO 3834, for example, regulate the quality requirements for manufacturing operations and define principles for the quality assurance of welded products.
Objective
In this seminar, you will learn how the interaction between design, production including quality assurance and material selection works in practice and how designers can control the quality of the end product. In connection with quality, you will learn about manufacturer certifications, e.g. according to the standards ISO 3834, EN 1090 for load-bearing components made of steel and aluminum and EN 15085 for rail vehicles. After the seminar, you will understand why weld seams are potential weak points and how this relates to structural changes in the heat-affected zone and the notch effect. The relationship between weld seam quality and the load-bearing capacity of the welded structure will also be explained in a very clear way.
You will recognize that the standard-compliant creation of production drawings according to ISO 2553 with adequate tolerancing according to ISO 13920 counteracts the occurrence of damage as well as their stress-compliant design and professional production. Case studies are used to show how welded structures are designed in practice in accordance with FKM and Eurocode.
