FATIGUE OF PLATES AND WELDMENTS IN HIGH STRENGTH STEELS.

Abstract

Studies were made on the fatigue behavior of HY-100 weldments and weldments in HY-130/150 steel. The physical properties and chemical compositions of the base metals are presented. The fatigue data for both materials were obtained using axially loaded transverse butt-welded specimens in the as-welded condition. Details of the test specimens are given. The net width at the test section was determined by the test stress cycle and the capacity of the fatigue machines. A MIL-12018 electrode was used for the HY-100 transverse butt-welded specimens currently under investigation. The fatigue tests were conducted on zero-to-tension stress cycles; the results are compared with data from similar tests of the HY-100 material welded with a MIL-11018 electrode. Metallurgical examinations of HY-130/150 weldments prepared with each of two welding procedures were made and the results are reported. Preliminary fatigue test data are reported for transverse butt-welded specimens using the two welding procedures.
