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。

Using metallographic analysis, original structure and surface deficiency were obtained, the influence of the structure on corrosion speed was settled, the surface macrography patterns of welded joint in different temperature and concentration were got. Microscopic patterns after corrosion in different condition were gained by SEM, though which the influence of temperature, concentration and structure on corrosion was easily observed.
