The e®ectiveness of weld joints primarily depends on the fusion of base metal, minimum heat- a®ected zone (HAZ) and lesser residual stresses. The severity of thermomechanical e®ects e.g. weld shrinkages and residual stresses is signi¯cantly minimized by narrow gap welding tech- nique over the traditional welding. This work describes the […]
