| 摘 要： | 坝后式引水压力钢管取消伸缩节后合拢焊缝接头形式有对接和搭接两种接头形式。对两种接头形式进行了试验研究,结果表明:对接和搭接两种接头形式都有各自的特点,对接接头形式优点较为明显,采用一些工艺措施可以减少焊接拘束应力和防止裂纹的产生,采用对接接头形式有利于引水压力钢管安全运行。 |
| 关 键 词： | 合拢焊缝 套管式接头 对接接头 拘束应力 |

| Abstract: | After canceling telescopic joint of penstock in the hydropower station at dam toe, the closure weld has two types including butt joint and lapped joint, two joint types are studied by experiment, the results showed that this two joint types have their characteristics respectively, butt weld has more advantages than lapped joint, adopting some technology methods, constraint stress by welding can be reduced and cracks can be prevented, it's evident that penstock can run safely using butt weld. |
| Keywords: | Closure weld Lapped joint Butt joint Constraint stress |
