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.

    本发明公开了一种热成型激光拼焊一体式门环及加工方法,涉及汽车制造领域,门环包括顶盖边梁、A柱、门槛、B柱下部和B柱上部,且所述顶盖边梁、A柱、门槛、B柱下部和B柱上部间依次通过激光焊接,且所述顶盖边梁上设有A柱补丁板,所述B柱上部上设有B柱补丁板。所述A柱补丁板与所述顶盖边梁间进行点焊连接,所述B柱补丁板与所述B柱上部间通过点焊连接。本发明在节约原材料节省的同时,单独排样落料也能够按照预设厚度要求保证各部件的厚度,满足门环不同位置的安全强度要求,保证汽车的安全性并减轻汽车重量。
