Third Partial Report on NRL Shock-Fracture Test for Welding Joints in Connection with Welding Test No. 302

Abstract

Eight semi-restrained groove double-vee ballistic pendulum test specimens were prepared at the Philadelphia Navy Yard in connection with Welding Test No. 302 and forwarded to the Naval Research Laboratory for testing. The performance in the NRL shock fracture test of the welded S.T.S. armor was considerably better than that of the welded low alloy ballistic steel. Inconclusive results were obtained in comparing Grade IV and Grade V electrodes. The plates welded in the flat position were somewhat better than those welded in the vertical position.
