This memorandum represents a combined effort by the U.S. Naval Applied Science Laboratory, Brooklyn, New York, and the Defense Metals Information Center to summarize new information on welding thick Ti plate. Thick plate of Ti continues to be of interest to the aerospace and defense industries for possible use in submersibles, armored vehicles, large space boosters, high-speed aircraft, and for pressure vessels. This memorandum generally is limited to information on welding Ti plate that is (1) at least 1 in. thick and (2) that is not covered by DMIC Report 185, The Status and Properties of Titanium Alloys for Thick Plate, June 14, 1963. The general requirements for welding Ti are not repeated here, since they are well documented in references mentioned in the inroduction to the memorandum. Sections have been prepared to cover material developments, welding-process developments, weld properties, and residual welding stresses. (Author).

Testing was completed on the first 2 experimental weldments of 2-in.-thick, commercially pure Ti plate. The 3rd, 4th, and 5th sets of the 2-x 4x 24-in. plates, which were machined to a number of variations of a modified double-V joint design, were welded, radiographed, sectioned, and tested. An optimum modified double-V joint design was decided upon for the machining and welding of the 2-x 15-x 30-in. plates into a 2-x 30-x 30-in. weldment. The best welding techniques developed during the welding of the first 5 experimental weldments were used. The X-ray radiograph of the weldment showed it to be free from porosity, cracks, and other defects capable of detection by this means of non-destructive inspection. (Author).

Experimental programs concerned with the oxidation of titanium and its alloys are reviewed and results compared with those predicted by theory. Wagner-Hauffe theory is used as the primary basis for comparison, and its inconsistencies are pointed out. Fifteen binary alloy systems involving titanium are covered, as well as a few ternary and commercial alloys. A short section discusses the effects of oxygen or nitrogen contamination on the mechanical properties of titanium and its alloys. (Author).

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).

Suitable out-of-chamber, manual and semi-automatic welding techniques have been developed for the fabrication of a titanium alloy pressure box of the type required for low cycle fatigue studies at the Marine Engineering Laboratory. These techniques may also be used for fabricating complex structural elements of heavy plate titanium. (Author).
