这篇文章论述了马氏体不锈钢CrNi16—5的焊接高水头混流式转轮的设计和制造。部分介绍了为满足现代转轮日益增长的需要而改进的制造方法。该产器基于计算机辅助设计和计算机辅助制造。简要描述了确定转轮所要承受的负荷所做的工作,以及在疲劳荷载下,根据焊接的特性,如何来适应这些特性要求。描述了残余应力和工作(负荷情况下)应力的测量及合适焊条的选择和焊接的验收标准。 This article discusses the design and manufacture of a welded high head Francis rotor for martensitic stainless steel CrNi16-5. Section describes manufacturing methods that have been improved to meet the growing needs of modern runners. The device is based on computer-aided design and computer-aided manufacturing. A brief description of the work done to determine the load on the wheel, and how to adapt to these characteristics under fatigue load, depending on the characteristics of the weld. Describes the measurement of residual stress and stress at work (under load) and acceptance criteria for the selection of suitable electrodes and welding.
