  1. The welding technology of francis turbine runners is optimized from the view of subsection welding and local heating by numerical simulation. the result shows that welding residual tensile stress appears in the weld and its area nearby, and peak stress appears in the dangerous area of blades after practising quondam welding technology ; welding residual tensile peak stress in the dangerous area of blades can be decreased by welding both ends earlier and then welding middle section later during subsection welding, and decreasing effect on welding residual stress of the subsection welding is related to the weld length of blade outlets and welding direction of each subsection ; decreasing effect on residual stress of the local heating is direct proportional to heating time, heating temperature, heating area, and inversely proportional to cooling area, and welding residual tensile peak stress in the dangerous area is decreasing trend earlier, and then increasing trend later with heated location increased

    本文利用數值模擬手段對轉輪的接工藝從分段和局部加熱兩個方面進行了優化,結果表明:採用普通工藝接時,葉片后殘余拉應力出現在及其附近區域,並且在葉片出水邊的熔合線附近(危險區域)出現了峰值;在採用優化的分段時,先兩端后中間的方法可以降低葉片危險區域的接殘余拉應力峰值,降低果與葉片出水邊各段的接方向關;局部加熱法降低轉輪危險區域殘余應力的果主要與加熱時間、加熱溫以及加熱面積成正比,與冷卻面積成反比,並且危險區域的殘余應力隨加熱區域的增大呈先降低后升高的趨勢。
