This report deals with the testing of seven large welded steel specimens similar in design to a square hatch corner of a ship. These were the last seven in a series of 26 such specimens which were tested to determine the performance of seven types of steel when built into a welded structure which had severe restraint to plastic flow due to a designed discontinuity. One of the last seven specimens was constructed of a 3-1/3 per cent nickel alloy steel and two from a low carbon steel having 0.82 per cent manganese. The others were made of three grades of plain carbon ship quality steel. Preheating at 400F was used on three of the specimens. The effect of preheating was very beneficial. The specimen constructed from nickel steel absorbed rather little energy before failure. This was attributed to the high yield strength of this material which prevented plastic flow of the plate before failure of the welded joints. (Author)
