航空发动机关键零部件及增材制造设备研发

- Master Thesis: Research on laser welding process of aluminum, which produced by traditional and additive processing methods.- Combined with the relevant data obtained during the internship, study the laser welding process of aluminum AlSi10Mg made with the additive SLM process.- Work in progress ...

- Through searching of 9 master thesis and 17 journal literatur related to 1000 to 7000 series aluminum materials, the laser welding process of different aluminum materials at the current stage was analyzed and reported.- According to the requirements of the follow-up master thesis, find out the optimal laser equipment for laser welding of Al-Si aluminum alloy and related experimental methods, such as: YAG solid-state laser, inert protective gas, welding wire and material pre-treatment methods and the solutions for low absorption rates, porosity and hot cracking problems.

- Mainly operating many different machines: punching and grinding machines, CNC lathe and milling machines, measure the workpiece and lay out the material, and familiar with the complete production process of the bearing cage.- Support the German company in receiving China Dick Machine Tool Co. Ltd in cooperation with the production requirements of the German company newly developed semi-automatic bearing lathe (DKCK S-200 series), technical advice and Chinese-German translations support.
