Abstract

In the present paper, a fatigue analysis for welded joints made of mild,
and high- and ultra-high-strength steel grades and post-weld-treated
with grinding and combined grinding and peening methods is carried out
using literature data. The 4R method was used to re-analyze the data
points considering material strength, residual stress, applied stress
ratio, and weld toe radius. The use of the 4R method, instead of local
fatigue strength assessment approaches, enabled residual stresses to be
taken into consideration and accurately predicted the fatigue strength
of joints in the as-welded and post-weld-treated conditions, including
grinding and combined grinding and peening methods.
