Laser welding of components of different thickness made of dissimilar metals

Abstract

The results of investigations into laser welding of components of different thicknesses produced from dissimilar metals are presented. The experimental results show that uniform heating of the weld edges is achieved by producing welded joints with a bead on the thin wall component, with the height of the bead 3–4 times greater than the thickness of the component. Experiments were carried out to investigate pulsed laser welding of components of different thicknesses made of dissimilar metals. The experimental results confirm that the mutual melting of the beads takes place without lack of fusion defects and burning in the welded joints only when the optimum dimensions of the beads are adhered to.
