The investigation described in this report is a direct continuation of work described in report SSC-43. The Ship Structure Committee directed further exploration of the relative effects of different welding procedures on the notch toughness of the welded joint as determined by the direct explosion test as follows: 1) Determine notch toughness of welded joints of a semi-killed and of a fully killed steel when welded with: a) Class E-7016 electrodes, and b) Submerged arc process, using two passes, one from each side. 2) Obtain a general indication of the relative effects on the notch toughness of welded joints of a fully killed steel, of the following factors: a) preheat of 150 deg F, b) interpass temperature, c) low temperature stress relief, and d) peening of all weld passes.
