Summary on Grant Application Form |
|
During the first IMI CEMWAM programme, an initial investigation of the feasibility of fusion welding processes for primary airframe structures was carried out. Work at Cranfield demonstrated that sound welds can be achieved in'h selected 2xxx and 7xxx series alloys using the TIG and Plasma processes. Consistent process performances have also been shown on Ti-6A1-4V. Independently, the potential of MIG welding has also been demonstrated, and a systematic baseline study is now proposed. This work seeks to extend the earlier feasibility study through a series of iterative steps enabling welding process improvement and airframe joint design to proceed in parallel. Attention will be paid to a number of critical considerations, including: start / stop control (influence on distortion and cracking), process control for variable heat sink geometries,. welding requirements for variable material thickness, and parameter selection for minimisation of component distortion. At the end of the first year prototype demonstrators will be constructed. Design and process modifications will then be carried out to improve on the limitations and problems encountered, prior to production of optimised demonstrators. The information generated will enable UK industries to critically assess the advantages..and limitations of arc welding technologies for airframe applications.
