Multi-objective Optimization of Weld Bead Geometry of Micro-plasma Arc Welded Titanium (Ti–6Al–4V) Alloy Sheets Using TOPSISBy M. Sumalatha, V.V.S. Kesava Rao
Abstract: Titanium alloys are used in the manufacturing of aero engine components for their attractive, combined properties such as lightness, good strength-to-density ratio, corrosion resistance. In the present paper, titanium (Ti–6Al–4V) alloy sheets are butt welded using micro-plasma arc welding. Peak current, base current, pulse rate, and pulse width are considered as weld input parameters and weld bead geometry parameters, namely front width, back width, front height, back height, are considered …
