This report supplies information on joining processes applicable to titanium and its alloys in sheet metal applications, primarily related directly to airframe construction. Although the material presented here does not cover all titanium joining processes, and omits such processes as plasma-arc, submerged-arc, electroslag, flash, and high-frequency resistance welding, the data presented cover materials up to 2-inches thick in some cases and the report should be useful to anyone seeking titanium joining information. The joining processes covered fall into five categories: welding, brazing, metallurgical bonding (diffusion and deformation bonding), adhesive bonding, and mechanical fastening. The fusion welding processes that are discussed in detail include gas tungsten arc, gas metal arc, arc spot, and electron beam. The resistance processes give extended coverage are spot, roll spot, and seam welding. (Author).

Titanium is a candidate as a structural material for all new tactical and armored ground vehicles, because of its high strength-to-weight ratio, excellent corrosion resistance, and inherent ballistic resistance. However, titanium as a structural material is much less mature than both steel and aluminum alloys, especially in the area of joining. While welding is the typical joining method for titanium, vacuum brazing is an option in areas that are difficult to access for welding as well as areas near other nonmetallic materials, such as ceramics. This work focuses on vacuum brazing of titanium (both Ti-6Al-4V and commercially pure titanium) and the effect of processing changes (alloy, temperature, pressure), including post-braze hot isostatic pressing, on mechanical properties and microstructure. This study will examine the joining of both plate materials as well as lightweight, periodic pyramidal core structures. Shear and tensile testing is performed to determine the strength/ductility relationship to the various processing routes. Microscopy (optical and SEM) is employed to quantify the degree of bonding and to examine the microstructural changes, both within the base materials and at the bond line, associated with the process variations.

Intermetallics have many metallic characteristics, including luster, and electrical and thermal conductivity. Ordered intermetallic structural materials have recently been the focus of many investigations. The physical and brazing properties of Ni–Al system intermetallics, Fe–Al intermetallics and Ti–Al intermetallics are presented in this chapter, including brazing methods, joint microstructure and corresponding mechanical strengths. The suitability of a variety of brazing filler metals for Ti–Al intermetallics is also discussed, and an extensive comparison is made between the brazing of traditional materials and those including more than three intermetallics.
