Rupture and growth of holes in the melt pool during laser keyhole welding of thin sheets

Abstract This study investigates the formation and growth of holes during laser keyhole welding of 100 μm thin 316 L stainless-steel sheets in overlap joints, represented by bead-on-plate welding of 200 μm thick foils. Using high-speed imaging, keyhole instabilities, promoted by...
