The invention provides a roof and side wall welding assembly structure comprising six parts which are a roof, a luggage mounting bracket, a side wall outer board, a front stand column upper reinforcing board, a middle stand column inner board roof side rail and a front stand column upper inner board. The roof is provided with a sunroof reinforcing ring and the edge of the reinforcing ring is provided with a welding block which is located between a connecting part of the roof and a connecting part of the side wall outer board. A connecting part of the front stand column upper inner board is provided with a first plug welding hole and the front stand column upper reinforcing board is provided with a welding block installing groove corresponding to the welding block. The installing groove is provided with a second plug welding hole. The front stand column upper reinforcing board is provided with a third plug welding hole corresponding to the first plug welding hole. A connecting part of the middle stand column inner board roof side rail is provided with a notch corresponding to the second plug welding hole. The roof and side wall welding assembly structure solves the problems of insecure welding spots, frequent cold solder joints, excessive spacing distance between welding spots, different welding operation and inconvenient grinding caused by using spot welding, and effectively improves the properties and modality of bodies in white.
