Fri, 08 December, 2023

TWI SEA proudly announces that Welding Programme Manager, Marzuqi has achieved a significant milestone by becoming the first NSIRC (National Structural Integrity Research Centre) student in Malaysia in collaboration with the University of Science Malaysia (USM).

"Embarking on a groundbreaking research journey, TWI SEA proudly introduces Marzuqi, our inaugural first NSIRC International student, transforming conventional welding expertise into advanced research skills. In the realm of welding, where benefits range from enhanced structural integrity to technological innovation, TWI is not just advancing; we are shaping the future. Looking ahead, we are eager to cultivate excellence by upskilling our dedicated staff and engineers globally, fostering a culture of continuous learning and innovation."

EurIng Prof Dr Gan Tat Hean, TWI Group Director

Marzuqi’s research focuses on the critical investigation of the relationship between grain structure alterations and discoloration in titanium (Ti-6AI-4V) welding, a topic of immense importance in industries such as aerospace and medical devices. The growing demand for lightweight hybrid structures has fueled the need for understanding and optimising the welding processes of titanium to ensure structural integrity, cost-effectiveness, and aesthetic quality.

"Marzuqi’s innovative research on titanium welding grain structure modifications and discoloration is crucial for aerospace and medical device industries. His drive to understanding these difficulties shows his passion for welding process knowledge. We congratulate Marzuqi on this milestone and look forward to his pioneering research generating disruptive solutions for improved titanium welding in industries that use these components."

The research, outlined in Marzuqi’s paper titled, "Investigating the Relationship between Grain Structure Alterations and Discoloration in Titanium (Ti-6AI-4V) Welding,” addresses the challenges posed by discoloration during titanium welding. The research aims to unravel the intricate connections between alterations in microstructure and the emergence of surface discoloration, providing insights into the causes, effects, and potential mitigation strategies.

The impact of Marzuqi’s research is vast, particularly in industries where titanium’s properties, including corrosion resistance and lightweight characteristics, are indispensable. Weight reduction in components, especially in aerospace applications, not only enhances efficiency but also aligns with environmentally responsible strategies by reducing carbon dioxide emissions.

Marzuqi’s research methodology involves a thorough exploration of the conventional Tungsten Inert Gas (TIG) welding method. The experiments include welding titanium samples using various parameters such as welding current, welding speed, and heat input. The research employs advanced techniques such as spectroscopy, colorimetry, and microscopy to quantify and understand discoloration, alterations in grain structure, and their impact on mechanical properties.

The findings of Marzuqi’s research are expected to pave the way for innovative welding solutions, offering industries guidelines and best practices for achieving superior titanium welds. The research not only contributes to the academic understanding of welding processes but also aims to bring about transformative changes in industrial applications, particularly in the aerospace and automotive sectors.

Marzuqi’s achievement as the first NSIRC student in Malaysia underlines TWI SEA’s commitment to fostering research and expertise in welding and materials science. The collaboration with the University of Science Malaysia reflects a shared dedication to advancing knowledge and addressing the challenges faced by industries relying on titanium-welded components.
