DTU Civil Engineering and Colorado School of Mines use neutrons to improve weld integrity of underwater wind turbine foundations.

Researchers Michael Joachim Andreassen (right) from DTU and Zhenzhen Yu from the Colorado School of Mines use neutrons at the Department of Energy’s Oak Ridge National Laboratory (ORNL) to investigate residual stresses expected to occur in the welds of offshore underwater wind turbine foundations.

"We’re studying residual stresses in really huge structures, especially supersized monopiles—enormous steel cylinders that form the underwater foundations for wind turbines. We want to look at the relationship between residual stress and varying thicknesses in the steel plates used in construction, by comparing two different welding methods,” says Michael Joachim Andreassen in the arcticle Neutrons Improve Weld Integrity of Underwater Wind Turbine Foundations at Oak Ridge National Laboratory's website.
