Abstract
An evaluation of the axial fatigue behavior of plain plates and full
penetration weldments in HY-lOO steel is presented. Transverse butt-welded specimens
welded with the MIL-11018 electrodes were found to contain minute internal
weld flaws which often serve as critical locations for fatigue crack initiation.
The weld flaws, although not detected by usual radiographic inspection, were
successfully located with the use of ul trasonic detection equipment. The ultrasonic
equipment was used also to study the initiation and propagation of fatigue
cracks in several test weldments, A preliminary investigation of the axial fatigue
behavior of HY-l30/l50 steel plain plates is reported.Bureau of Ships, U.S. Navy.Contract NObs 92226Project Series No. SR-007-01-01, Task 88
