Weldability of 2519-T87 Aluminum Alloy

Abstract

Test results show that 2519-T87 is weldable to itself and to 5083- H131. A wide variety of filler metals, weld parameters, and post-weld heat treatments were studied to determine the effect on weld mechanical properties, hot crack susceptibility, microstructure, and ballistic integrity. Previously reported 2519-T87 weldment ballistic failures have been discovered to be invalid. New ballistic weldments of 2519-T87 welded to itself were successfully qualified to the shock test in MIL-STD-1946. Keywords: Weldability, Aluminum alloys, Mechanical properties, Armor. (JES)
