Impact of Welded Joint on Cyclic Strength of Low-Alloyed Steels

Abstract:

In this paper we considered changing the structure of the metal near the weld joint. The samples were tested under cyclic load with the asymmetry of the cycle of R=0.8 - 0.9. Influence of the weld on the cyclic strength is assessed. A methodology for determining residual life at any operation periods is developed.
