Basic parameters were established for joining titanium alloy using the resistance spot-weld-adhesive bonding weldbonding PROCESS. Design of test parameters for evaluation of static strength of weldbond joints in titanium alloy required that first consideration be given to the probable use of the developed process. Since a high percentage of titanium used in joints of military aircraft would involve areas either exposed to high stress andor elevated temperatures, strength at elevated temperatures was given prime consideration. Test results analysis showed that weldbond joints were superior in strength at room temperature as compared to all other joints tested. Weldbond joints andor spot-weld joints were superior in strength in all categories from room temperature to 400 F as compared to other joints tested. Mechanical fasteners plus adhesive showed the third highest strength as compared to other joints. Structural adhesive bond joints were generally inferior in strength to all other joints from room temperature through 400 F. Author-PL
