Zirconium can be fusion welded to a number of other reactive and refractory metals including niobium, hafnium, vanadium, tantalum and titanium. Fusion welding of zirconium to titanium can result in a weld exhibiting varying final properties which are unpredictable and generally non-reproducible. In the case of zirconium to titanium welds the corrosion resistance is generally less that that of either of the parent metals. In addition, the mechanical properties of the weld are highly variable. This paper presents information on the corrosion resistance and mechanical characteristics of the zirconium-to-titanium fusion weld. The effect of heat treatment is also discussed. This particular weld combination is not generally suitable for fabrication of equipment for use in the chemical processing industry (CPI).
