The invention discloses an integral impeller blade semi-finishing method for removing residual stress with the aid of laser. The surface of an integral impeller blade to be machined is subjected to laser shot-blasting strengthening treatment by adopting pulse laser beams after a thermal treatment procedure and before a conventional semi-finishing procedure, and a surface deformation layer caused by the laser shot-blasting strengthening treatment is removed by milling, so that the residual pressure stress and the residual tensile stress respectively produced by the front and rear procedures are counteracted with each other, deformation produced after the stress of the blade is released is effectively controlled, micro cracks are reduced, and the machined integral impeller blade has good stability and reliability. The method is applied to stress removing mechanical cutting machining of complex impeller blades having various structures.
