We use mechanics testing method like stretch and bend to test the 3mm magnesium alloy(MB3) after friction stir welding. The stretch sample can show no less than 70% of raw materials performance when the condition is suitable: R= 1500r/min,v = 90mm/min,R/v=16.7 and F=1470N. Curve intensity of the joint reaches 90.2% and 83.0% at obverse and inverse curve separately.

利用拉伸、弯曲等力学测试手段对搅拌摩擦连接的3mm厚MB3镁合金板进行机械性能检验，检验结果为：在使用焊接合理工艺参数R=1500r／min，v=90mm／min，R／v=16.7，F=1470N的情况下，拉伸试样70％以上断裂于母材，接头正弯与背弯强度分别可以达到母材的90.2％和83.0％。
