摘要	Numerical simulation on Francis turbine runner＇s welding temperature field and welding stress field is carded out on the base of solving the problem of welding heat source＇s movement along any spatial routes and the problem of heat elimination between the complicated blade and air. The evolvement law of welding stress and the distribution of the stress field after welding are obtained. The results indicate that the peak value of the welding residual stress appears on the outlet edge of blade near the contact area between blade and band or blade and crown. Associated with the distribution of the runner＇s working stress, the invalidation reason of the Francis turbine runner is explained.
