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 ...
