Imad Eddine Guira

Visiting PhD Student, National Polytechnic School Algiers

Imad Eddine Guira is a visiting PhD student with the CCWJ from February 2026, joining from the National Polytechnic School Algiers in Algeria. His work focuses on welding of stainless steel-copper joints, with emphasis on microstructure evolution, defect formation, and mechanical properties using laser and arc welding processes.

Jimena Vela Avitúa

Visiting Student, Universidad Nacional Autónoma de México

Jimena Vela Avitúa is a visiting student with the CCWJ from July 2026, joining from the Universidad Nacional Autónoma de México (UNAM). Her work focuses on the microstructural evolution, mechanical properties, and failure behavior of Cr–Mo alloy steel welds (1.25Cr–0.5Mo / 2.5Cr–1Mo) produced using Hybrid Laser-Arc Welding (HLBW) and GTAW under various preheat and post-weld heat treatment conditions. Her research includes metallographic preparation and microstructural analysis, mechanical testing, chemical and fractographic analysis, and in-situ process monitoring of welding processes.

Kazuki Miyamura

Visiting Student, Hiroshima University

Kazuki Miyamura is a visiting research student with the CCWJ from July 2025, joining from the Program of Mechanical Engineering at Hiroshima University in Japan through Hiroshima University’s ECBO (Engineers Cross Borders) / Joint Research Program. His current research focuses on computer vision applications for welding training and weld quality control using a compact head-mounted camera; laser wire additive manufacturing of aluminum alloys with dissimilar filler materials; and the development of a high-accuracy, high-efficiency laser wire additive manufacturing process using the hot-wire…
