Job Title:

Research Scientist

Department:

Engineering | Materials Science and Engineering

The Ohio State University, College of Engineering, Department of Materials Science and Engineering, is seeking a Research Scientist.

Minimum Required Education is a PhD's Degree in  Mechanical, Welding, Metallurgy, Materials Engineering, or a similar field. Candidate must have 7-11 years of relevant research experience with 10-15 years of relevant research experience preferred.

The Research Scientist should be fully experienced within the Research Laboratory environment. The Research Scientist will serve as a resource for Research Technicians, Graduate Research Associates, Undergraduate Research Assistants, and Undergraduate Students. The Research Scientist will apply their industry knowledge and a thorough understanding of the Research being performed to lead research and work independently.  The Research Scientist will work on complex research projects of large scope within the Department.  The Research Scientist will be able to complete routine work independently; while only requiring general guidance on new research initiatives and projects.

Specific research areas the Research Scientist will be involved in include the development of materials joining processes and metal additive manufacturing, creating new solutions in process automation, and materials analysis for the application of advanced materials. The Research Scientist must have comprehensive experience in all main scopes of welding research, including advanced welding processes, metallurgical analysis, and process/materials simulation and modeling.

From the welding process perspective, the required experience includes, but is not limited to:

• Gas Metal Arc Welding (GMAW) and variations:
  • Pulsed current (both DC and AC)
  • GMAW with controlled short circuit
  • Cold Metal Transfer (CMT)
  • Surface Tension Transfer (STT)
  • Regulated Metal Deposition (RMD)
  • Controlled Carbon and Carbon Dioxide (CCC)
  • High-performance GMAW for deep penetration applications
• Gas Tungsten Arc Welding (GTAW) and variations:
  • Pulsed current
  • GTAW with dynamic wire feeding (reciprocating wire)
• Plasma Arc Welding (PAW) for high-performance applications (high welding speed and deep penetration)
• Friction Stir Welding
• High-Speed filming techniques for comprehensive evaluation and study of welding processes
• Acquisition and interpretation of welding electric signals including voltage, current, power, wire feed speed, and gas flow rate.
• Experience with offline programming for additive manufacturing in 6-axis robots is a differential.

The welding metallurgy and materials science knowledge and expertise required includes:

• Metallographic samples preparation for several systems including but not limited to:
  • Steels
  • Stainless Steels
  • Ni-based alloys
  • Ti alloys
  • Al Alloys
  • Refractory alloys
• Optical microscopy analyses
• Scanning electron microscopy analysis, including:
  • Energy-dispersive X-ray spectroscopy (EDS)
  • Electron Backscatter Diffraction (EBSD) map analysis, including data analysis (IOM, HKL, Mtex)
  • Prior grain reconstruction
• Corrosion testing of metallic samples
• Charpy impact test
• Hardness testing, including: Macro, Micro and nano-indentation
