However, the creep fracture of medium strength match joint, located in the low strength base metal remote from the weld interface, showed a ductile fracture character.

中强匹配接头蠕变断裂位置在远离焊缝界面的低强度母材区，呈延性断裂性质。

The results show that the defects in the weld such as interface reactant and pore are the key factors to reduce the material weldability.

研究发现，焊缝中存在的界面反应物、气孔缺陷，是导致该种材料焊接性显著降低的主要因素。

Then use the coil ring machine rolled into a circle, with the electrode to weld the interface firmly, welding mouth to carry out X spectroscopy.

然后用卷环机卷制成圆圈，用焊条把接口处焊接牢固，焊口处要进行X光谱检验。
