Abstract
Low cost resistance butt welds between a similar Ti–6Al–4V alloy couple have been fabricated using a Gleeble thermomechanical simulator. The optimisation of the key bonding parameters (pressure, time, temperature and environment) required to produce high quality joints with near parent properties is discussed. Metallographic sections, chemical composition and microhardness traverses across the bond line are presented. The mechanical response of the bonds was assessed under monotonic tensile loading conditions. The suitability of this solid state diffusion technique for the fabrication of engineering components is discussed.
