Abstract
The increase of fatigue resistance by applying post weld treatment methods offers great potential for reducing the use of materials and costs for monopiles. Specifically, in the automated monopile manufacturing chain, automated processes such as deep rolling are a suitable option. This paper presents results of deep rolling as a new post treatment method to increase the fatigue strength of welds. In order to quantify the influence of deep rolling on the weld geometry, measurements of a laser line sensor are presented. With the help of this new evaluation method, a correlation between the initial weld geometry and the effectiveness of deep rolling can be demonstrated.
