Services

Fatigue tests of coated bolts M36 and larger with corrosion and pretension

Bolts in different sizes and with coatings, ranging from m36 to M72, can bet tested for fatigue. The influence of corrosion and pretension will be considered. The surface conditions of corroded bolts can be measured by 3D surface scans and will be considered in the fatigue assessment. The focus is on bolted connections as used in offshore wind structures.

Fatigue assessment of numerous steel connections and construction details

Various steel connections and construction details can be tested for fatigue, such as welded connections, bolted connections, grouts or truss nodes.
