Friction stir welding of fuel containers

这项合同拨款将集中在使用搅拌摩擦焊制造铝基容器上。将开发用于连接燃料容器的铝结构的工艺参数，并随后验证原型组件的完整性。这将是该技术在AA6000系列铝容器上应用的首次研究，因此必须确定搅拌摩擦焊连接这些材料的可行性，以便将该技术推广到工业规模。这将涉及到设计和测试合适的焊接工具和焊接参数来生产薄壁搭接焊缝。这项工作将对汽车和航空航天行业具有更广泛的适用性，并将为建立这种连接技术的更一般规范奠定基础。

This Engage grant will focus on the fabrication of aluminium-based vessels using friction stir welding. The processing parameters will be developed to join aluminium structures for fuel containers, and subsequently verify the integrity of prototype components. This will be the first study of the application of this technology for AA6000 series aluminium vessels, and so feasibility of joining these materials by friction stir welding must be established in order to pursue the technology at an industrial scale. This will involve the design and testing of a suitable welding tools and welding parameters to produce lap welds in thin sections. The work will have broader range applicability to both the automotive and aerospace industry, and will be the basis for establishing more general specifications for this joining technology.
