The utility model discloses a welded type differential assembly for a drive axle. The differential assembly comprises a front differential shell, a back differential shell, as well as cross axles and epicyclic gears which are arranged inside the differential shells. The differential assembly is characterized in that a conjunction plane of the front differential shell and the back differential shell is circumferentially and symmetrically provided with four weld grooves, i.e. the interiors of the front and back differential shells are provided with the cross axles, the cross axles are provided with the epicyclic gears thereon, and the two shells are relatively positioned and welded into one body. Without the need of a screw bolt for fastening, the differential assembly has simplification and lightweight, omits fastening parts, and saves cost.
