| 摘 要： | 针对纵缝采用搅拌摩擦焊、环缝采用VP-TIG熔焊工艺的箱底进行液压试验,并在试验过程中监测各典型焊缝位置的应变响应,结果显示箱底上搅拌摩擦焊缝和熔焊焊缝交叉形成的"T"型接头区域在试验中最先进入屈服,说明该位置材料的屈服强度较低,是箱底承载的薄弱环节。

| Abstract: | Compression resistance experiment was carried out with water on tank bulkhead which was welded by friction stir welding(FSW) on longitudinal weld and by variable polarity tungsten inert gas welding(VP-TIG) on orbicular weld, and the strain brought by press was measured on typical weld position. The result shows that the intersection of FSW and VP-TIG weld has lower yield strength, which enters into the plastic deformation state at first, is the weak position of the tank bulkhead. |
