Weld Seam Monitoring for Wind Turbines
Wind turbines are subject to complex systems of variable loads, this makes them particularly susceptible to damage caused by fatigue and cyclic loading. Once initiated this damage will continue to worsen until complete failure occurs, due to either stress from the damage exceeding the ultimate strength of the material, or the damage reaches severe levels and a critical crack fracture forms. Monitoring of any critical welds on a turbine provides the operators with an early warning indicator, so should excess stress and fatigue be exerted on the welds and early stage microscopic cracks begin to form, operators have the opportunity to investigate and take precautionary actions to avoid catastrophic failure of the structure. Catastrophic failure of a turbine leading to collapse can be devastating and costly, and debris can be scattered over several hundred yards from the site of the turbine. Well documented in the news was the collapse of a turbine in Northern Ireland, showing the extent of damage that can be caused when these structures fall.
