The report presents the results of the first phase of a study of full scale welded joints a study of the fatigue and static properties of butt welds. The purpose of the tests reported were to compare the fatigue and static properties of butt welds produced with the E6010 and the E7016 electrodes. Two types of butt weld specimens were tested the longitudinal butt welds were tested with the applied stress parallel to the direction of welding, whereas the transverse butt welds were tested with the applied stress perpendicular to the direction of welding. The butt welds have been tested either with the reinforcement on or with the reinforcement removed by grinding. The specimens were subjected to a stress cycle which varied from a low tension of about 2000 psi to a maximum tension which was of such magnitude that failure generally occurred between 100,000 and 2,000,000 cycles. In order to more thoroughly understand the behaviour of butt welds subjected to repeated stresses, an extensive review of the fatigue tests of butt welds conducted previously at the University of Illinois is included in the report.
