The stirring friction welding tool capable of welding with rolling utilizes the rolling balls uniformly distributed around the transition shoulder to weld a weldingsurface of the lower clamping body. The stirring friction welding tool capable of welding with rolling utilizes the rolling balls uniformly distributed around the transition shoulder to weld a weldingline and a near-welding region while rolling, realizes the conversion of surface tension on the surface of the welding line to comprehensive stress, controls the welding deformation, eliminates the s line and a near-welding region while rolling, realizes the conversion of surface tension on the surface of the welding line to comprehensive stress, controls the welding deformation, eliminates the scrap rubber at both sides of the welding line and further refines particles on the surface of the welding line.crap rubber at both sides of the welding line and further refines particles on the surface of the welding line.al stress, welding deformation and scrap rubber.
