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.
