DOI: 10.1016/j.applthermaleng.2017.10.081
Abstract: Abstract Welding-induced angular distortion is a typical out-of-plane distortion, which brings negative effects on the joints’ quality. Therefore, the selection of appropriate process parameters to minimize or control welding-induced distortion under uncertainty has become of… read more here.
