摘要： A system of components includes a first component including a first joint portion, and a second component including a second joint portion abutting the first component. At least one of the first and second components is formed from cast iron. The first joint portion and the second joint portion, when aligned, form a V-Shaped groove having a groove opening, a groove bottom angle of between about 10° and about 20° and a weld nugget envelope defined therebetween. The groove opening is wider than an outer diameter of a filler wire employed to form a metallurgical bond between the first component and the second component.

摘要： In a method of manufacturing a differential device, a hub of a ring gear is press-fitted to a flange from a first bearing boss side, then a press-fit portion between the flange and the ring gear is equally divided into a plurality of divided regions arranged along a peripheral direction, and simultaneously the divided regions are welded. Accordingly, the press-fit portion between the flange and the ring gear can be efficiently welded while welding distortion of the ring gear is eliminated or reduced even in a case where work windows of a differential case cut into a side surface of the flange on the first bearing boss side to form recessed portions.
