On basis of numerical simulation, the optimized weling technological has been vadidated and adjusted by plane test, results show that residual stress of both ends welded in advance can be decreased by the interspace welded later, and decreasing effect is the most obvious in the 50mm range of the interspace ; for local heating, it is 60mm from the edge of heated area to decrease residual stress
通過平板試驗得到了分段焊與局部加熱合理工藝參數,並在此基礎上,對轉輪的焊接殘余應力場進行了調整與控制,使葉片出水邊危險區域附近產生了較大的殘余壓應力,且轉輪整體的殘余應力水平低於轉輪材料屈服極限的三分之一。
