主 题：Laser-arc welding Aluminum alloy High-strength steel Cu interlayer Adhesive
摘 要：Aluminum alloy 6061 and high-strength steel Q460 were joined by laser-arc-adhesive hybrid welding technology successfully.A Cu alloy interlayer was added between Al alloy and high-strength *** effect of the adhesive on laser-arc-adhesive hybrid welding of Al alloy to high-strength steel was *** optical microscope,scanning electron microscope and electron probe micro-analysis were applied to observe the microstructural evolution and phase transition at Al-Fe interface of laser-arc-adhesive hybrid welded *** results showed the maximum tensile shear strength of the joint without adhesive was 256 *** adding adhesive,the maximum tensile shear strength reached 282 *** combination of the mechanical bonding and the metallurgical effect could improve the mechanical *** shape of the joint in Al alloy changed into a canine-like *** was no porosity in welds because the molten pool of Al alloy and the special keyhole phenomenon of laser welding provided a channel for the decomposed gas to escape from fusion zone.
