About

Ghalib Tham is a welding engineering researcher whose work centers on Gas Metal Arc Welding (GMAW) processes, weld bead geometry prediction, and thermo-mechanical analysis of welded structures. His research makes significant contributions to the optimization of welding parameters and the understanding of structural behavior in multi-pass welding applications, particularly relevant to industries such as shipbuilding and steel construction. Among his most recognized contributions is his investigation into the correlation between welding parameters and bead geometry in T-fillet joints, covering challenging positions including downhill (3F) and overhead (4F) configurations. Using articulated welding robots and materials such as ER70S-6 solid wire with carbon steel coupons, his work provides practical predictive frameworks that help engineers achieve consistent, high-quality welds. His 2013 study on angular distortion in multipass welding employs thermo-elastic–plastic finite element modeling validated experimentally, offering valuable insight into deformation control — a critical concern in precision fabrication. With his most-cited papers accumulating 16 citations each, Tham's research serves as a useful reference for welding engineers and academics seeking data-driven approaches to process optimization. His blend of experimental rigor and computational modeling makes his work particularly valuable for students entering manufacturing and structural engineering fields.
