Laser　fusion　brazing　welding　was　proposed.　Galvanized　steel/AA6061　lapped　joint　was　obtained　by　laser　fusion　brazing　welding　technique　using　the　laser-induced　aluminium　molten　pool　spreading　and　wetting　the　solid　steel　surface.　Wide　joint　interface　was　formed　using　the　rectangular　laser　beam　coupled　with　the　synchronous　powder　feeding.　The　result　showed　that　the　tiny　structure　with　the　composition　of　alpha-Al　and　Al-Si　eutectic　was　formed　in　the　weld　close　to　the　Al　side.　And　close　to　the　steel　side,　a　layer　of　compact　Fe-Al-Si　intermetallics,　including　the　Al-rich　FeAl3,　Fe2Al5　phases　and　Al-Fe-Si　tau　1　phase,　was　generated　with　the　thickness　of　about　10-20　mu　m.　Transverse　tensile　shows　the　brittle-fractured　characteristic　along　to　the　seam/steel　interface　with　the　maximum　yield　strength　of　152.5　MPa　due　to　the　existence　of　hardening　phases　tau　1　and　Al-Fe　intermetallics.
