Effects of post treatment on the fatigue strength of weldment
용접부 강도특성 미치는 후처리 영향
- Published : 2004.11.01
Abstract
Effects of the post treatment on the fatigue strength of a bead-on-plate weldment were investigated in order to improve fatigue strength of the weldment. The post treatment applied were the grinding of weld toe and hammer peening at the weld toe. The fatigue strength of the weldment after post treatment increases. It is attributed to the decrease of the residual stress and the maximum stress at the weld toe by the post treatments. Based on the result, the principal factor controlling the fatigue strength of the weldment was identified as the toe shape of the bead-on-plate weldment.
