The invention discloses a thermal forming tailored blank laser welding integrated door ring and a machining method, and relates to the field of automobile manufacturing. The door ring comprises a top cover edge beam, a column A, a doorsill, a column B lower portion and a column B upper portion, the top cover edge beam, the column A, the doorsill, the column B lower portion and the column B upper portion are sequentially welded through laser, a column A patch plate is arranged on the top cover edge beam, and a column B patch plate is arranged on the column A patch plate. A B column patch plate is arranged on the B column upper part. The A column patch plate is connected with the top cover edge beam in a spot welding mode, and the B column patch plate is connected with the upper portion of the B column in a spot welding mode. According to the method, raw materials are saved. Meanwhile, the thicknesses of all parts can be guaranteed according to the preset thickness requirement through independent stock layout and blanking, the safety strength requirements of different positions of the door ring are met, the safety of an automobile is guaranteed, and the weight of the automobile is reduced.
