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。 - 2
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。 - 3
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。
