Daniele Calista

Materials Engineering

Daniele Calista is a PhD Candidate with the CCWJ, where he has been conducting research since 2022. His thesis involves understanding the fundamentals behind the high-frequency electric resistance welding (HF-ERW) of tubular products, including line pipe, casings, and conduit. Through examining how welding parameters influence defect development, Daniele aims to improve the integrity and performance of HF-ERW products. His research supports the application of these materials in demanding conditions, particularly for renewable energy initiatives like hydrogen transport and CO₂ sequestration.…

Xinrui Liu

Materials Engineering

Xinrui Liu is a PhD Candidate with the CCWJ who joined in the Fall of 2021. Prior, he worked as an intern with the CCWJ in 2018. His current research centres around developing experiments and models to better understand the defect formation mechanism of friction stir welding. Through this work, he aims to improve the efficiency and reliability of this critical process, with applications across various industrial sectors such as aluminum panel welding for the battery tray of an electric vehicle.

Gurbarn Singh

Materials Engineering

Gurbarn Singh is a Welding Engineer and Ph.D. candidate at IIT Madras currently conducting research as a visiting student at the CCWJ through a Joint Doctorate Program since 2021. His research focuses on microstructural factors contributing to poor toughness performance in the high-frequency electric resistance welded bondline of API 5L X65 line pipe steel. This work aims to enhance the structural integrity and reliability of welded pipelines in critical energy applications. Gurbarn is a licensed Professional Engineer (P.Eng.), CWB Level 3 Welding Inspector, and CWB Retained Welding Engineer.
