Weld seam calculation and
design
Rely on precise weld seam calculations. The design is focused on safety, service life, and cost-effectiveness – tailored to your requirements.
Long-term safety for your weld seams
Control loads. Design joints safely.
A strength verification of welded joints is essential for the reliable design of load-bearing structures – whether in mechanical and plant engineering, automotive engineering, or steel construction. Both static peak loads and cyclic loading from recurring forces or thermal effects can significantly influence service life.
The calculation takes into account geometry, stress distributions, and weld configurations – standards-compliant, e.g., according to the FKM guideline or based on experimental characteristic values. The goal is to identify weak points early and ensure the long-term load capacity of your welded joints.
Weld seam verifications are essential when ...
Your safety – our responsibility
structural welds are located in highly loaded areas – for example, in the load path – and must be assessed as potential weak points.
load-bearing welded joints are subjected to cyclic loading and proof of fatigue strength is required.
failure due to crack formation under real operating conditions is to be avoided – especially for safety-relevant components.
the design is to be optimized economically with regard to material usage, weld geometry, and manufacturing, without compromising safety.
the stress and deformation behavior of the welded joint is critical to the overall function of the structure.
Benefits of weld seam calculations
Measurable benefits. Verifiable quality.
With virtual simulations and sound calculations, we support you in developing products faster, safer, and more cost-effectively. Our standard: robust results you can rely on.
Prevention of component failure
A strength verification of the weld seams can ensure that the component withstands the applied loads. This protects people and property.
Sizing of weld seams
We determine the required dimensions of the weld seams to ensure a safe and load-bearing component. Especially under cyclic loads, a prior estimate is often difficult.
Optimization of weld seams
If thick plates are part of your design, optimizing the a-dimension can often significantly reduce welding effort and thus your costs.

Frequently Asked Questions (FAQ)
Quick answers. Clear solutions.
Here you will find answers to the most common questions about our services.
Which standards can be applied for the strength verification of weld seams?
We carry out weld seam verifications, among others, in accordance with the FKM guideline, DIN EN 1993, and other industry-specific standards. Customer-specific requirements or international standards (e.g., AD2000, DIN EN 13445) can also be taken into account. Please contact us if your standard is not listed!
Can weld seams be reliably verified in an FEA simulation?
Yes, modern FEA simulations enable a realistic stress analysis at and near weld seams. For a standards-compliant verification, however, suitable assessment methods must be applied – such as structural stress approaches, notch stress concepts, or hot-spot methods. We combine FEA results with proven verification methods to provide robust, auditable statements on weld seam strength.
What information do you need to carry out a weld seam verification?
For a weld seam verification, we require design data, material properties, load information, and details of the welding process. Subsequent assessments are also possible. Contact us – we will be happy to review your application in detail.
