Weld Calculation and
Design
Rely on precise weld calculations. The design focuses on safety, service life, and cost-effectiveness – tailored to your requirements.
Lasting Safety for Your Welds
Master loads. Design connections safely.
A strength verification of weld connections is crucial for the reliable design of load-bearing structures – whether in mechanical and plant engineering, automotive technology, or steel construction. Both static peak loads and cyclic stresses from recurring forces or thermal influences can significantly impact service life.
The calculation considers geometry, stress distributions, and weld configurations – in accordance with standards, e.g., FKM guideline, or based on experimental characteristic values. The goal is to identify weak points early and to secure the load-bearing capacity of your weld connections long-term.

Static Strength Verification
A static strength verification checks whether a component can withstand the intended loads safely and permanently.
Fatigue Strength Assessment
Fatigue describes the gradual failure of components under repeated, cyclic loading.
Bolt Calculation
Bolt verifications check the load-bearing capacity of preloaded and non-preloaded connections – depending on the type of load.
Weld verifications are essential when ...
Your Safety – Our Responsibility
constructive welds are located in highly stressed areas – such as in the force flow – and must be evaluated as potential weak points.
load-bearing weld connections are subjected to cyclic stress and proof of fatigue strength is required.
failure due to cracking under real operating conditions is to be avoided – especially for safety-relevant components.
the design is to be economically optimized regarding material usage, weld shape, and manufacturing, without compromising safety.
the stress and deformation behavior of the weld connection is crucial for the overall function of the structure.
Benefits of Weld Calculations
Measurable Benefit. Verifiable Quality.
With virtual simulations and well-founded calculations, we support you in developing products faster, safer, and more economically. Our claim: reliable results you can count on.
Prevention of Component Failure
With a strength verification of the welds, it can be ensured that the component withstands the acting loads. This protects people and assets.
Dimensioning of Welds
We determine the required dimensions of the welds to ensure a safe and resilient component. Especially with cyclic loads, a prior estimation is often difficult.
Optimization of Welds
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 frequently asked questions about our services.
Which standards can be applied for the strength verification of welds?
We perform weld verifications according to the FKM guideline, DIN EN 1993, and other industry-specific standards, among others. Customer-specific requirements or international standards (e.g., AD2000, DIN EN 13445) can also be considered. Please contact us if your standard is not listed!
Can welds be reliably verified in an FEA simulation?
Yes, modern FEA simulations enable realistic stress analysis on and near welds. However, for a standard-compliant verification, suitable evaluation methods must be applied – such as structural stress approaches, notch stress concepts, or hot-spot methods. We combine FEA results with proven verification procedures to provide reliable and verifiable statements on weld strength.
What information do you need to perform a weld verification?
For a weld verification, we need design data, material properties, load specifications, and information on the welding process. Subsequent evaluations are also possible. Contact us – we will gladly examine your application in detail.
