Review of fatigue data for welds improved by tungsten inert gas dressing
Source abstract
Abstract
Abstract Experimental fatigue data points for the welds improved via the tungsten inert gas (TIG) dressing method have been extracted from the existing literature. The extracted fatigue data includes experimental points for longitudinal attachments, transverse non-load carrying welds, butt joints and T-joints. In total, 311 published test results for weld details with various yield strengths ( 272 ⩽ f y ⩽ 1100 MPa ) and stress ratios ( - 1 ⩽ R ⩽ 0.2 ) are presented and analysed. A step-wise increase in the fatigue strength based on the specimen geometry and the steel grade is proposed with an S–N slope of m 1 = 4 . All of the fatigue data for constant amplitude loading are found to be in good agreement with respect to the proposed design curves.
