When this alloy was welded autogeneously the presence of significant amounts of α martensite was observed, recommending looking for another solution. In the early trials a V joint design was used but distortions and defects were detected in the welds when multi-pass procedures were considered. Consequently, for the remaining weldments K or I joint configurations were selected. Initially, Ti-6Al-4V wire was preferred in order to match mechanical properties with base material but no significant improvement was found leading to consideration of using a less alloyed filler metal. Different commercially pure titanium filler metals have been employed to optimise the performance of the fusion zone of electron beam weldments. In a second paper [1] the influence of the welding procedure on the mechanical properties of the various joints will be discussed.7enginfo:eu-repo/semantics/restrictedAccessjournal article10.1016/j.vacuum.2009.08.003Electron beamMicrostructural characterizationTitanium alloysWelding procedureInstrumentationCondensed Matter PhysicsSurfaces, Coatings and Filmshttp://www.scopus.com/inward/record.url?scp=70350573539&partnerID=8YFLogxK
