CAP1400堆芯补水箱支承柱组件与封头焊接技术研究
|
摘要
支承柱组件与下封头的组焊是制造国核压水堆示范工程2#机组堆芯补水箱的关键技术难点。通过1∶1模拟件的焊接和技术分析,掌握了控制焊接变形的焊接方法、焊接参数、焊接顺序、防变形工装设计等综合焊接技术。将这些焊接试验成果应用于实际产品的焊接,焊接结果满足设计要求。
Welding of support column components and lower head was a key technical issue for manufacturing reactor core makeup tank of national nuclear pressurized water reactor sample project 2# machine set. By welding and technical analysis of 1∶ 1 simulating part,comprehensive welding techniques have been mastered,such as welding method of controlling deformation,welding parameters,welding order and deformation resistance tooling design. The weld test results have been applied to products welding in practice and the weld results satisfied the design requirements.
