英文摘要	Laser welding-brazing of 5A06 aluminum alloy and galvanized steel sheet with filler powder was carried out. The obtained butt joint exhibited dual characteristics. The interfacial properties and microstructure of the joints examined using Scanning Electron Microscopy (SEM), Energy Dispersive Spectrometer (EDS) and X-ray Diffraction (XRD), and the tensile strength was measured. Results show that a non-uniform intermetallic compound (IMC) with serrated shape is formed at the interfacial layer, which is composed of Fe2Al5 and FeAl3. The thickness of the IMC layer varies from 2.5~7 μm, and it increases with the laser power. At the top surface of the galvanized steel the IMC layer reaches the thickest. Using this laser welding-brazing method with special filler powder, the IMC thickness can be controlled to less than 10 μm, and butt joints with certain tensile strength can be obtained under appropriate welding parameters. © 2016, Editorial Board of Jilin University.
