Aluminium and titanium alloys are widely used in aerospace and automobile sectors for their light weight and corrosion resistance properties while titanium is mainly for high strength to weight ratio and high temperature properties. However, both the alloys suffer from porosity formation during welding and similar problems are found in arc DED deposits and also in welding of deposits prepared using any additive methods.
The project seeks to address the issue of porosity formation in aluminium and titanium welds and DED deposits. Also, a potential lack of fusion in the case of titanium welds and arc DED deposits. Representative arc DED parts will be prepared using a modified TIG welding process followed by characterisation using x-ray computed tomography and macro examination.
The improved approach will provide the following benefits:
