大型水电上冠堆焊过程中的变形控制方案

Deformation Controlling of Heavy Hydropower Crown During Build-up Welding Process

合理安排焊接工艺、防变形工装、专用加热辅具、消应热处理措施,成功解决了上冠大面积堆焊过程中的变形问题。

By preparing the welding process reasonably, adopting the deformation preventive tooling and the spe- cialized heating appliance, and taking the stress relief heat treatment process as measures, the deformation problem of crown during the build-up welding process in the range of large area has been solved successfully.
