Reliable application of recognized calculation methods
Main focus
- Properties of welded joints and why damage can occur to welded structures
- Verification concepts for the calculation of weld seams (nominal, structural, notch and effective stress concept) and their areas of application
- FEM modeling techniques for the verification concepts
- Weld seam calculations according to FKM, Eurocode, DVS 1612 and IIW recommendations with examples
- Use of the latest tools for weld seam evaluation with examples
- Relationship between weld quality (e.g. evaluation group according to ISO 5817) and stress resistance of weld seams based on DVS 0705
- Increasing the fatigue strength of weld seams through the use of weld seam post-treatment methods (e.g. higher frequency hammering with PIT)
On the subject
Welded joints play an important role in mechanical engineering, plant construction, rail vehicle construction, pressure vessel construction and many other industries. It is therefore essential for designers and engineers to have extensive knowledge of the calculation and design of welded structures. Various standards and guidelines can be applied to ensure the load-bearing capacity (static and dynamic).
It is therefore extremely important to understand these regulations and to know which can and should be used for the specific welded component. Especially with regard to product liability and component optimization (weight reduction), also against the background of cost reductions, the importance of weld seam calculation according to the current state of the art is definitely increasing.
Objective
In this seminar, you will learn how welded structures can be economically designed and calculated in practice in accordance with FKM, Eurocode and DVS 1612. The main area of application for FKM strength verifications is in mechanical engineering and related areas of industry. The strength verifications according to Eurocode (EC 3 steel construction) are used for steel structures and DVS 1612 in rail vehicle construction.
In addition to the different verification concepts - nominal, structural, notch and effective stress concepts and their areas of application - you will also learn about the use of state-of-the-art software tools (FKM inside ANSYS, Limit, MDESIGN weld) using various examples. You will understand how and why the load-bearing capacity (static and dynamic) of weld seams depends, among other things, on their quality of execution (e.g. evaluation group according to ISO 5817). The fatigue strength of weld seams can be increased enormously with various weld post-treatment processes, which is already taken into account in various regulations.
