Arc Welding of Armor Single Vee and Double Vee Butt Welds in 1 Inch Homogeneous Armor

Abstract:

To determine and compare the resistance to penetration and the resistance to impact of a single vee and a double vee butt joint in 1 inch homogeneous armor plate welded with the bevels preclad with 2520, a filler metal of 2520, and a hard facing electrode on the surface layers. The resistance to penetration of the single vee butt joint and the double vee butt is approximately the same there being but 6 fs difference in the maximum resistance of the two joint fired at with .50 cal. A.P. ammunition. The ballistic limit obtained was 2619 fs for a single vee joint and 2625 fs for a double vee joint. The resistance to shock of the single vee and double vee butt joints in this test could not be definitely determined because the homogeneous armor Brinell 444 shattered, leaving the weld intact.
