- Abstract
The hole-drilling strain gage residual stress investigation reported in this paper was initiated to determine residual stress field in proximity to weld beads. The study was conducted on an ultrasonic welded joints prepared from Romanian "A" type naval steel plate samples. Experimental data demonstrates a step stress gradient in the vicinity of the weld bead. Residual stresses from the vicinity of weld bead are compressive because all the thin plates have low stiffness.
