OLIVER (Optimised Laser welding Implementation Via Enabling Research

点击翻译按钮获取中文摘要

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.
