Welding sequence effects on residual stress distribution in offshore wind monopile structures
Residual stresses are often inevitably introduced into the material during the fabrication processes, such as welding, and are known to have significant effects on the subsequent fatigue crack growth behavior of welded structures.

| Summary: | Residual stresses are often inevitably introduced into the material during the fabrication processes,
such as welding, and are known to have significant effects on the subsequent fatigue crack growth behavior of
welded structures. In this paper, the importance of welding sequence on residual stress distribution in
engineering components has been reviewed. In addition, the findings available in the literature have been used
to provide an accurate interpretation of the fatigue crack growth data on specimens extracted from the welded
plates employed in offshore wind monopile structures. The results have been discussed in terms of the role of
welding sequence in damage inspection and structural integrity assessment of offshore renewable energy
structures. |
