Entropy generation : a basis to investigate the effect of preheating on residual stresses in weldments

The residual stresses produced due to violent thermal gradients in welded plates, cause significant problems such as brittle and fatigue fracturing. Several methods are suggested for reducing the residual stresses and undesirable deformations.
