Sipokazi Mabuwa, graduating today with a Doctor of Engineering in Mechanical Engineering, has pushed herself. She has managed to finish her studies in two years, and this is a historical record after overcoming several obstacles on her way to graduation.
Mabuwa started her Doctoral study in 2020 and finished her work in 2021. Moreover, she has produced 17 journal articles within these two years. Mabuwa has also managed to create her first MEng graduate in 2021. “She is the first female to obtain this qualification in the history of the Mechanical and Mechatronic Engineering Department,” the principal supervisor, Dr Velaphi Msomi, remarked.
Her research title is: Development of new FSP method for enhancing the mechanical properties of FSW and TIG welded dissimilar aerospace aluminium alloy joints. Mabuwa’s research focuses on friction stir welding and friction stir processing.
Reflecting on her journey, Mabuwa said she wanted to register in 2019 but learned it was not possible due to her Master’s submission being late for consideration for the April 2019 graduation.
“Some might have been discouraged, but not me. Instead, I used the same stumbling block as my stepping stone. I started idealising my PhD topic with my supervisor, Dr Msomi, and what was expected of me as a PhD student (planning and deliverables),” she explained.
From the topic she was going to pursue, it became pretty clear that some of the materials she would use were only available internationally. After learning this, Mabuwa started buying through the CPUT requisition system using her supervisor’s research account. That process took about seven months. The material was purchased from China, and certain functions were to be followed, like clearing it before it was delivered to the institution. However, during that waiting period, Mabuwa started working on her proposal until her supervisor was convinced it was of a “PhD student quality”; then, she saved it for the following year. Next on her list was writing a review paper based on the study she would be doing the following year. The paper was submitted to one of the approved journals of the Department of Higher Education and Training (DHET) by December. “After submitting my review paper while waiting for it to undergo all the processes I wasn’t waiting for, I used that time to write chapters 1 and 2 of the thesis in 2019,” Mabuwa continued.
When she registered in January 2020, Mabuwa had all the necessary materials, consumables, and supervisor-student planning. “All I did was to execute so that I meet all the expectations set out, including publications of about 35 articles published in approved journals, out of which 17 articles were directly from my stud,y and five were international collaborations with well-known researchers in my field, while the rest was based on utilising other available materials from the FSW group storage stores.”
Mabuwa said this was done for practising purposes to learn more about the technique she was to use. During this time on the side, she was writing chapter 3. “One of my biggest traits was that I love learning, and I always strived to make my work more competent in the eyes of the international researchers, that alone pushed me so hard to prove that I was one of them. One of the things that stuck in my mind was and is that at PhD level, you are like a brand ambassador of two entities - that is, yourself and your institution. So, whenever I was writing a paper myself, it was like sending a message that this is who Sipokazi Mabuwa is, and this is what CPUT is. I love myself very much to brand myself as a researcher of poor quality. Hence, on each paper, I gave it my all, thoroughly researched whatever angle of approach I was to use, and consulted those who published in my areas of interest.”
Msomi described Mabuwa as a timid individual “but also a very dedicated, hard-working student”. “She is also a fast learner, and this is judged by different research techniques that she learned in a year or less. She was not the type of student who would want to be monitored. I am very proud of what she has achieved in the past two years, and I can confidently say she has impacted the field. This is judged because she has been a reviewer for many international journals. I see her growing to higher heights in the next few years.”
Reflecting on her success, Mabuwa, born in the rural Mnandi location In Willowvale, Eastern Cape, said: “I feel very overwhelmed and excited. I have made my mark, and I am very pleased with myself. All glory goes to God.”
“The support I have received from CPUT has been wonderful; they have never closed doors on my requests…They were very supportive in every part of this journey, and I also thank Dr Msomi; he was the one who showed me all the doors when we ran out of funds.”
