Do you want to contribute to the development of metallic components for wind energy?  

We seek a flexible, open-minded and self-motivating person to work in the field of microscale characterization of cast iron.

Job description
The research position is part of a project funded by the Innovation Fund Denmark, which seeks to develop a game changing welding technology that will enable assembly welding and repair welding of large scale cast iron components for wind turbines. The successful applicant will be a member of a larger team of university researchers working closely together with the major companies in this project, which include welding institutes, foundries and wind turbine manufacturers. Welding will be carried out by industrial expert partners in the project where the weldments will be characterized by state-of-the-art NDT techniques. 

Your primary responsibilities and tasks will be to:

  • Use 3D mapping with X-ray computerized tomography and scanning electron microscopy to analyze the size and shape of the graphite nodules as well as any cracks and porosities within the heat-affected zone.
  • Establish a correlation between the microstructural observations and the welding parameters in order to optimize the welding procedure.
  • Provide tomography reconstructions and statistical data on microstructural features as input data for thermo-mechanical fatigue modelling performed by other researchers in the project.
  • Collaborate with researchers and technicians in the project and disseminate the results in peer-reviewed journals

The applicant must have experience in characterization techniques (e.g. X-ray tomography, SEM, ect). Experience with digital image processing will be considered as an advantage. Previous experience with welding research may be beneficial, but is not required.  

The successful candidate is well-motivated, hardworking, eager to seek and share knowledge and willing and able to work as part of a team as well as through interdisciplinary collaboration with industrial partners and across sections in the DTU Wind Energy department.

The candidate should be confident in both written and spoken English and as a formal qualification; the candidate must hold a PhD degree (or equivalent) preferably in Materials Science, Engineering or Physics.

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice.
