To provide rim-disk tack welding equipment for a full face wheel having high productivity, wherein the release from heavy working can be realized, it is unnecessary for each normal welding machine to be provided with a centering fixture for a rim and a disk, and also, the centering accuracy of the rim and the disk is high.

(1) The rim-disk tack welding equipment 10 is arranged on the upstream side in the direction of a work flow than a normal welding machine 11 of subjecting a rim 1 and a disk 2 to normal welding, and in which the carrying-in of the disk 2, the carrying-in of the rim 1 and the carrying-out of a tacked rim-disk 7 are performed by robots 12, 13. (2) The rim-disk tack welding equipment 10 is provided with: a centering fixture 20 of centering and fixing the disk and the rim; and a tack welding torch 30 of subjecting the disk and the rim to tack welding.
