摘要
管道焊接工装是根据研究需要设计的一种试验设备,主要完成核电安装焊接过程中对组队管道实现0~90°的翻转和0~360°的旋转.为校核其工装设备的强度及变形对激光热丝焊焦深的影响,将其翻转和旋转过程简化为7个工况,利用有限元分析软件得到该管道焊接工装设备的应力值与变形值,计算并分析强度及变形是否符合要求,得到的计算结果为同类试验激光焊接工装设备的设计提供了有效的设计指导.
The pipeline welding tooling is a kind of test equipment designed according to the research needs. It mainly achieves 0 - 90 degree turning and 0 - 360 degree rotation of the team pipe in the process of nuclear power installation and welding.In order to check the strength of the tooling equipment and the effect of deformation on the depth of focus of the laser wire,the turning and rotating process is simplified to seven working conditions.The Stress value and deformation value of the welding equipment are obtained by finite element analysis software. Calculate and analyze whether the strength and deformation are in conformity with the requirements. The calculation results provide an effective design guide for the design of similar test for laser welding equipment.
