Research Scholar, Mechanical Engineering, Beihang University 2006.1-Present Team leader of High Efficiency Arc Welding Research, Beihang University RESEARCH INTERESTS Our research focus on high frequency pulsed welding of aluminum alloys, titanium alloys, superalloys and stainless steels using gas tungsten/metal arc welding and plasma arc welding (GTAW/GMAW/PAW); welding metallurgy of aluminum alloys, titanium alloys, superalloys and stainless steels; weld formation and solidification behavior. Currently we have a large research activity on additive manufacture (AM) using weld build up for aerospace applications. This activity is led by our Associate Professor Baoqiang CONG and we have four Ph.D. and several master students as well. The research is also partly carried out in collaboration with Prof. Stewart in Cranfield University, UK. The focus for this work has so far mainly been high strength aluminum alloy but we are also moving on to titanium parts. The objective would be to contribute to the research effort with a view to pushing the technology.
