My project is a summer research fellowship with Antonio Ramirez at the Edison Welding Joining Center focused on arc welding and printing. The research position is alongside the TEK8 program which includes a course in the fall to develop engineering design challenges for K-8 students at Metro Middle School.
The research fellowship solidified my desire to pursue further research focused on metal additive manufacturing. I realized that although research can be boring at times with writing papers and preparing posters, experimentation activities can make up for it. The research topic I focused on was on an additive manufacturing process I never heard of, expanding my view of the possibilities of additive manufacturing. The TEK8 program made me realize that explaining research and its applications to a wider audience is important. It gave me a larger appreciation for educators and a clearer path to simplify complex topics into an understandable way.
During the research fellowship, I learned how to use CAM software to program a welding robot to create additive manufacturing parts such as the Ohio State logo and lab logo under the guidance of a postdoctoral student. Given that there were defects in the parts, I identified that a tool lacked in the software to identify the optimal stepover distance between welding beads for additive manufacturing. This led to me doing experiments changing welding parameters and stepover distances. Data collected from these experiments were used in multiple regression analysis in Excel to identify optimal stepover distances for different welding parameters. I presented my work at a summer research consortium and continue to work for the lab during the school year for further developments of my research project including using machine learning.
During the TEK8 program, I took a semester-long class to learn how to develop an engineering design challenge related to my summer research for sixth grade students. The design challenge I developed involved using playdough and modeling clay as weld beads and using them to create additive manufacturing parts in various ways. When presenting my design challenge in the classroom, I presented background information about additive manufacturing and welding, led the design challenge, and led cleanup and reflection. I also helped other students present their design challenges.
My experiences have affected me tremendously. I am now on the research map for welding and additive manufacturing given my work during the research fellowship. With my new relationships with professors, postdoctoral students, and graduate students in my field of interest, I can expand my opportunities and continue to develop as a researcher. Additionally, the TEK8 program has reinforced my desire to serve my community by helping students understand engineering. I will continue to consider service when conducting engineering work.
This transformation is significant because it made progress on three of my life goals. My first goal is going to graduate school and the research I conducted through my project helped me prepare for more serious research in graduate school. My second goal is doing meaningful engineering work and the TEK8 program allowed me to make a difference in my community through my engineering research. My third goal is to advance my engineering intellect and the transformation has given me real hands-on experiences using my developing technical and communication skills. The transformation has developed me into a leader prepared for significant contributions in graduate school.
