Mitigation of welding distortion and residual stresses via cryogenic CO2 cooling - a numerical investigation [PDF]
, 2008 Fusion welding remains the most common and convenient fabrication method for large, thinplate welded structures. However, the resulting tendency to out-of-plane distortion exacts severe design and fabrication penalties in terms of poorer buckling ...
