About

Engin Karaca is a materials scientist and welding engineer whose research focuses on advanced laser welding technologies and the metallurgical behavior of high-performance titanium alloys. His work centers on the application of robotic Nd:YAG fiber laser welding systems, with particular emphasis on the widely used Ti-6Al-4V alloy — a material critical to aerospace, biomedical, and defense industries. Karaca's most significant contribution lies in systematically investigating how process parameters and thermal treatments influence the microstructure and mechanical properties of laser-welded titanium joints. His 2017 study on robotic fiber laser welding of Ti-6Al-4V, which has garnered 31 citations, demonstrated the effects of varying heat input conditions on weld quality, providing practical guidance for industrial applications. Building on this foundation, his 2018 work explored the influence of pre- and post-weld heat treatments — including stress relieving, solution treatment, and aging — on joint performance, earning an additional 10 citations. Together, these contributions advance the understanding of how to optimize robotic laser welding processes for titanium alloys, making Karaca a notable voice in precision manufacturing and materials joining research.
