Patent ID: 7509739

Claim:
A method of manufacturing a full face vehicle wheel comprising the steps of: providing a wheel rim with one opening brim thereof formed to be a flange portion while the other opening brim is formed to be a peripheral joining end; providing a wheel disk with the periphery thereof formed to be a flange portion for supporting a tire bead sidewise, with said peripheral joining end being configured to be welded to the back surface of said wheel disk, providing the back surface of the wheel disk in advance with an annular joining groove; providing the peripheral joining end of the wheel rim in advance with an inside slope peripheral surface; seating and positioning said peripheral joining end on the bottom surface of the annular joining groove, thereby forming a welding heat confining annular region as a void surrounded by an inside groove wall of the annular joining groove, a bottom surface of the annular joining groove and the inside slope peripheral surface of the peripheral joining end; and welding the annular joining groove to an edge of the peripheral joining end at an outside surface of the wheel rim, such that weld metal is formed to fill the welding heat confining region and the wheel disk and the wheel rim are joined.
