For the study of the weldability of new-typed Mg-1Al-xSn-0.3Mn (x=1,3) magnesium alloys, the plates of extruded Mg-1Al-xSn-0.3Mn (x=1,3) magnesium alloys with a thickness of 2.8 mm were friction stir welded by butt. And the microstructure and properties were tested and analyzed by X-ray non-destructive test, OM, SEM, EDS, microhardness and tensile test. The results show that the above-mentioned magnesium alloys could be successfully butt-welded without any defect by friction stir welding, the microstructure in the NZ was fine and equiaxed, and some grains in the TMAZ were elongated in the form of bars. Moreover, the tensile strength of the friction stir weld could reached over 85% that of the base material and the HAZ at advancing side of the weld had the lowest hardness.
