Abstract:
Wires of AlCuLi alloys belonging to the family 2060 have been produced by powder pressing and extrusion of the green compacts, obtaining bars. The bars were drawn to obtain the wire, which was deposited on a 5083 substrate by PMD. Previously, the parameters were optimized with commercial wire of 2319 alloy. The parameters studied were: current (120 -240A), travel speed (100 -180 mm|min), wire feed speed (0.8 -1 m|min), plasma gas flow (0.8 – 1 m|min) and different atmospheres (Ar, Ar|He15, ArHeN-70|0.015). The optimum parameters were applied to deposit the wires obtained by PM. The results obtained have been compared to typical porosity in Al alloys, which is reduced by pre-heating (> 200 ºC) the substrate prior to welding. Li content losses have been observed in the drawing stage about 60 %wt. However, the Li amount remains during plasma welding process in quantities closed to the 72 %wt.
