| Abstract: | Welding residual stress greatly influences the fatigue character of Francis runners and also influences on the stability and safety of hydro turbine. The testing of welding residual stress is performed on a large turbine's runner by hole drilling. The results of the test is compared between the ahead anneal and the post anneal after welding. |
