"Laser Weldability of Nickel Alloys"
Laser welding is increasing in industry as a viable joining technology, though limited parameter development and potential weldability issues for many alloys discourages industrial adoption for high precision, high throughput welding. The automation and precision of laser beam welding (LBW) can reduce manufacturing costs while increasing productivity when welding parameters have been optimized. The objective of this study is to develop weld parameters that produce high quality welds for a selection of austenitic materials, and to control the formation of potential welding defects such as porosity and hot cracking.Degree Pursued:
Master of Science in Metallurgical Engineering
Estimated Graduation Date:
Jonathan is from Colorado and has bachelor’s degree in Metallurgical engineering from Mines. His interests focus on applying fundamental metallurgical principles to engineer solutions for challenges related to materials and metallurgy. While earning his undergraduate degree, Jonathan participated in an NSF funded REU program where he got experience with thin film semiconductors at North Carolina state university. This experience helped Jonathan further realize his interests in academic research, which he continued at Mines in the ASPPRC. The undergraduate research experience introduced him to new lab techniques including thermo mechanical testing, metallography, and some x-ray diffraction and microscopy at Mines, and with Ramman spectroscopy at North Carolina State. Jonathan was able to apply this experience in the field with two industrial internships at Dow chemical in Deer Park TX, and Chevron Energy Technology Company in Richmond CA. These internships gave Jonathan valuable experience in failure analysis, corrosion, fabrication, and professional skills. Because of the knowledge gained in these combined experiences, Jonathan is pursuing master’s degree in welding engineering, where he will continue to build his knowledge of fundamentals of metallurgy while applying them to furthering an industrial process.
