报告题目：Development of Welding, Joining and Additive Manufacture in Cranfield University
报告人：Prof. Stewart Williams




报告人简介：Prof. Stewart Williams is the Chair in Welding Science and Engineering and Director of the Welding Engineering and Laser Processing Centre (WELP). His main research activities are focused on additive manufacture and laser processing. Additive manufacture research is targeted at large scale engineering structures using the wire plus arc additive manufacture (WAAM) process. A multi project multi-client programme has been put in place, WAAMMat, aimed at maturing the technology so that it can be exploited by industry. Laser processing research is based around using fundamental material interaction parameters for different processes. This is being applied to industrial problems such as laser hybrid welding of pipelines and laser cutting. Pulsed laser research is targeting problems such as dissimilar welding, composite processing and peening.
Under Prof. Stewart’s leadership the Centre has a developed a diverse research program as outlined below:
1. Large scale additive manufacture (or 3D printing) of engineering metallic structures featuring
2. Laser processing – the Centre is lead partner for fusion processes in the EPSRC Centre for innovative manufacture in laser based production processes
3. Residual stress control, management, and measurement for both welding and additive manufacture
4. Dissimilar material joining – carbon fibre composite to titanium, aluminium to steel, titanium to stainless steel
5. Weld process and additive manufacture modelling including linear friction welding
