The proposed knowledge exchange is to transfer R&D into automatically joining by welding ultra thin wall advanced aerospace alloy small diameter tubing. Sourced directly from STFC funded research into low mass cooling systems; the technique, processes and knowledge will enhance modern aerospace and hybrid vehicle turbine manufacture by facilitating the removal of heavy fuel and cooling line connectors currently adopted by manufacturers. Reliable high strength welded joints are only achievable on thin wall aerospace alloy tubes through automated processes, all currently very costly and do not allow for simple in-situ installation of components. Reduction in the use of connectors in turn will allow for more compact turbine design and higher reliability. Savings made by the enhanced reliability of light weight connector less fuel and cooling systems will allow the efficiency gains sought after by gas turbine market consumers.

拟议的知识交流是将研发工作转移到通过焊接超薄壁先进航空航天合金小直径管自动连接方面。直接来源于STFC资助的低质量冷却系统研究;技术、工艺和知识将通过促进去除制造商目前采用的重燃料和冷却管线连接器来增强现代航空航天和混合动力车辆涡轮机制造。可靠的高强度焊接接头只能通过自动化工艺在薄壁航空航天合金管上实现，目前所有这些都非常昂贵，并且不允许简单的原位安装部件。减少连接器的使用又将允许更紧凑的涡轮机设计和更高的可靠性。轻量连接器的可靠性提高、燃料和冷却系统减少带来的节省将使燃气涡轮机市场消费者追求的效率提高。
