Graduate Studies for Welding Engineering

Statement of Purpose

"Arcs and Sparks!" was my understanding of welding at the beginning. Surprisingly, now I am applying the graduate studies for welding engineering which is the most fascinating area in engineering in my heart. What happened in the past three years? I have been on my own way to explore the world of materials science and engineering since the childhood. I grew up besides the SJ Petroleum Machinery Co., influenced by many engineers, I had a natural interest in such activities as hands-on practice, solving problems and making small objects gradually. Satisfyingly, I can always find my way.

After I went to Huazhong University of Science and Technology to study materials processing and control engineering, I became interested in various advanced manufacturing and processing techniques especially the Selective Laser Sintering (SLS), which could easily make complex geometries directly from digital CAD data. Because of my excellent performance and great enthusiasm, Prof. Yusheng Shi, a leading expert in addictive manufacturing, accepted my application to join his laboratory when I was a sophomore. I teamed up with four senior students, aiming to improve the system of selective laser sintering. We designed CAD models and made theoretic analysis. Working with senior students and graduates improved both my practical and theoretical skills, like operating of instruments and equipments, and fundamental theory of laser processing. Meanwhile I noticed that in many cases macroscopic properties were linked to microstructure. Thus understanding the effect of microstructure on the time evolution, response, and reliability of material properties was important. A lack of the relevant knowledge intrigued me to consider learning mor...

Actually, the more deep-going in materials process, the more I feel I need more training to become a successful researcher. That’s why I choose to continue my study on materials engineering, especially laser process technology. Your outstanding program, which is ranked among the best in the United States, plays a pioneering role in materials engineering and provides a nurturing and challenging environment. From Dr.Liu I heard a lot about life in Columbus, which is very attractive to me and I believe that the courses and research opportunities available in your program can best train me for the realization of my goals, challenge my personal beliefs and educational background, enable me to contribute to the academic atmosphere in my own way and create the "Arcs and Sparks!" in my mind.
