EVALUATION OF 2014-6061 ALUMINUM ALLOY WELDMENTS, HEAT TREATED AND AGED AFTER WELDING,

Abstract

Based on test results, the following conclusions were reached: For a 99-percent confidence level, the following are the expected design parameters when stops, starts, tacks ground out, and tacks welded over are included: 40,000 psi -- 0.05-in. material; 36,400 psi -- 0.125-in. material; 36,400 psi -- 0.25-in. material; Tensile elongations of 7.5 percent are typical for 0.05- and 0.125-in. material; however, the minimum elongations are 8.5 percent for 0.25-in. material; The recommended heat treatment for the bimetal junction is solution heat treatment at 950 = 10 deg F with a water quench, followed by an aging treatment at 350 = 10 deg F for eight hours, and subsequent cooling in air. The soaking times required for various sheet thicknesses are: < 0.032 in., 20 minutes; > 0.032-in. but < 0.10 in., 45 minutes; and > 0.10 in., 60 minutes. (Author)
