Deformation heterogeneity in laser-welded Eurofer
Fusion Engineering and Design, 2020 Abstract The suitability of a post-weld heat treatment is often measured in terms of reducing residual stress and/or ensuring hardness homogeneity. Here we use digital image correlation to quantify the localised deformation behaviour of laser-welded Eurofer-97 both with and without a normalising and tempering heat treatment.

Welding deformation produced by two-pass welding
Welding International, 2008 Multilayer welding is considered to be an accumulation of two-pass welding, and it was clarified that the basic factors of welding deformation were produced by two-pass welding. From comparison between the experimental results and numerical analysis, it was found that the numerical analysis method used in this research was very accurate to predict the ...
