We develop solutions which enable you to improve welding processes in your applications. Additionally, we support you in evaluating welded joints: was the welding done correctly? Did any cavities, pores or welding mistakes occur and/or was the welding incomplete? Did you create unwanted residual stresses?
During operation we evaluate a joint’s safety and life expectancy, especially for high temperature applications. We also consider the extreme environment of power plants, including aggressive atmospheres and changing temperatures.
We rely on our broad range of know-how to answer our clients’ questions. We simulate the welding process in order to calculate the resulting structure and residual stresses. Subsequently, we develop procedures to reduce the component’s warping. We optimize post weld heat treatments to prolong the components’ working life. Using a detailed mechanical characterization under conditions similar to operation we can define weld strenght reduction factors, especially for high temperatures. Furthermore, we can determine the remaining lifetime of cracked welded joints. Our expertise is also useful in evaluating joints between different metals: our clients gain vital information and solutions for the improvement of their joining processes, thus prolonging the components’ working life.
