Global warming can be reduced by controlling emissions in motor vehicles.Lightweight aluminum materials can lower the engine work so as to reduce fuel consumption.The effect of dwell time on mechanical properties and microstructure friction stir spot welded AA1100 with particle interlayer Zn were investigated.The Cargo Trousers result shows that the particle interlayer Zn affect to the mechanical properties.

The tensile shear load friction stir spot welded AA1100 with particle interlayer Zn is higher than hart of without particle interlayer Zn.In line with tensile shear load that the hardness of friction stir R18 spot welded Al with particle interlayer Zn got the higher hardness than of without particle interlayer Zn.The addition of particle interlayer Zn reduce the hook defect and spread in the aluminum matrix as solid solution.
