The invention relates to the technical field of automobiles, in particular to a rear longitudinal beam assembly, a welding method and an automobile. The rear longitudinal beam assembly comprises a longitudinal beam upper reinforcing plate in a frame shape; an inner supporting frame which is arranged in the longitudinal beam upper reinforcing plate, wherein the inner supporting frame and the inner wall face of the longitudinal beam upper reinforcing plate are welded to form an inner reinforcing plate assembly; a rear longitudinal beam which is omega-shaped, wherein an internal reinforcing plate assembly is inserted on the rear longitudinal beam, and the rear longitudinal beam is welded with the internal reinforcing plate assembly; a longitudinal beam lower reinforcing plate which is omega-shaped, and is arranged on the longitudinal beam lower reinforcing plate in an inserted mode, wherein the longitudinal beam lower reinforcing plate and the rear longitudinal beam are welded to form the rear longitudinal beam assembly part; and a casing pipe which is arranged on the rear longitudinal beam assembly part in a penetrating mode, and the casing pipe is welded to the rear longitudinal beam assembly piece. The problems that the casting pipe falls off and a suspension lock bolt loosens can be solved.

    本发明涉及汽车技术领域,尤其涉及一种后纵梁总成、焊接方法和汽车,后纵梁总成包括纵梁上加强板,所述纵梁上加强板呈框形;内部支撑架,所述内部支撑架设置在所述纵梁上加强板中,且与所述纵梁上加强板的内壁面焊接形成内部加强板总成;后纵梁,所述后纵梁呈几字形,所述内部加强板总成插设在所述后纵梁上,所述后纵梁与所述内部加强板总成焊接;纵梁下加强板,所述纵梁下加强板呈几字形,所述后纵梁插设在所述纵梁下加强板上,所述纵梁下加强板与所述后纵梁焊接形成所述后纵梁总成件;套管,所述套管穿设在所述后纵梁总成件上,所述套管与所述后纵梁总成件焊接。本发明能够解决套管脱落,悬置锁栓松动的问题。
