OLIVER (Optimised Laser welding Implementation Via Enabling Research

目前全球民用航空业面临的社会经济压力正在增加钛在航空结构中的使用。用现有方法生产零件会导致低效的买飞比(高达20：1)，这正变得越来越不经济(高材料成本和劳动密集型；导致高重复成本、长交货期和设计约束)，并推动了对通过近净成形焊接工艺制造结构的需求。激光焊接正在成为首选工艺，因为它可以以比其他焊接工艺快得多的速度生产出高质量和高性能的低变形焊缝。OLIVER项目将进一步发展激光焊接钛及其在结构航空航天组件中的应用方面的知识，同时通过发展英国供应链和原始设备制造商的英国制造能力来利用这些知识。Oliver项目包括两个OEM案例研究，它们代表了待开发技术的第一个上市机会。进一步的案例研究将展示激光焊接革命性钛复合材料中支柱部件的能力。

Current socio-economic pressures on the global civil aerospace industry are increasing the utilisation oftitanium in aero-structures. Production of parts by existing methods leads to inefficient buy-to-fly ratios (ashigh as 20:1), which is becoming increasingly uneconomical (high material cost & labour intensive; leading tohigh repeat costs, long lead times & design constraints) and driving the need for structures to be fabricated bynear-net-shape welding processes. Laser welding is emerging as the process of choice since it can produce lowdistortion welds of good quality and properties at significantly faster speeds than other welding processes. TheOLIVER project will further develop knowledge in laser welding titanium and its application to structuralaerospace assemblies, and at the same time exploit this knowledge by developing UK manufacturing capabilityboth within the UK supply chain and OEMs. Project OLIVER includes 2 OEM case studies which represent first-to-market opportunities for the technologies to be developed. A further case study is included which willdemonstrate the capability of laser welding a strut component in a revolutionary titanium-composite.
