| Abstract Scope |
Linear Friction Welding (LFW) is a solid-state joining process offering new opportunities of cost reduction and quality improvement for aerospace titanium part manufacturing. The process produces in a few seconds high integrity joints with fine grain, hot-forged microstructure and narrow heat affected zone.
The LFW process reached a high enough level of maturity, robustness and reliability to be ready for mass production of blisks (“blade disks”) for aircraft engines. It is now being developed for aircraft structural parts in aluminum and titanium alloys. This process allows not only to manufacture a given part at a lower cost, it also opens new part design possibilities that were not available with traditional manufacturing processes. The LFW process is explained through physical aspects, process parameters, mechanical characterization of the joint and microstructural data. Several LFW aerospace applications are introduced and evaluated through feasibility, weight reduction, post-weld operations and overall cost savings. |
