Journal ArticleDOI
Prospects of laser beam welding and friction stir welding processes for aluminum airframe structural applications
TL;DR: In this article, laser beam welding (LBW) and friction stir welding (FSW) are applied to high-strength aluminum alloys used in aircraft industry and displays their advantages compared with the riveting technique regarding structural integrity, weight and material savings.
Journal ArticleDOI
Experimental and numerical investigation of residual stresses in laser shock peened AA2198
TL;DR: In this article, the effect of the laser power density and focus size on the residual stress field of an AA2198-T8 has been investigated using the finite element method.
