At present, most of the existing automobile driving axle housings adopt a steel plate stamping and welding manufacturing technology, and the axle housing is mainly formed by welding half shells, an axle tube, a reinforcing ring, a rear cover, accessories and the like. The circumferential weld of the axle housing axle tube and the shell is a close-weight weld, and if the axle housing axle tube and the shell fail, accidents such as vehicle failure, side turning and the like can be caused, so that the life and property loss of personnel is caused. The product design requires that the welding line must be 100% welded through, the defects of cracks, incomplete welding through, burnthrough and the like cannot exist, and the axle housing fatigue bench test is required to be used for examination.
