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.

The results showed that the fracture toughness of the weld of HFW pipe was lowest.The value of absorbed energy of HFW weld was closely related to the heat treatment process.But the fracture toughness of fusion zone of submerged-arc welded jointer,its microstructure was coarse granular bainite,and was lower than the other locations of heat affected zone;and with the increasing of steel strength,the effect of welding heat cycles on the pipeline steel became stronger,and form coarse microstructure in fusion zone leading to decrease fracture toughness.

结果表明，高钢级管线钢高频焊接焊缝处的断裂韧性最低，其冲击功大小与热处理工艺密切相关；而埋弧焊接热影响区断裂韧性在熔合线处最低，其主要原因是此处的组织为粗大的粒状贝氏体，而且强度越高焊接热循环对管线钢的作用越强，在熔合线附近更容易产生粗大组织，使断裂韧性降低。
