The invention relates to the technical field of vehicles, in particular to a thermal forming door ring, a thermal forming door ring machining method and a vehicle. The thermal forming door ring comprises an A column lower edge beam, an A column upper edge beam, a B column upper edge beam and a B column lower edge beam. The A-column upper edge beam and the A-column lower edge beam form a first welding seam after laser tailor-welding, and the A-column upper edge beam and the B-column upper edge beam form a second welding seam after laser tailor-welding; a third welding seam is formed after the B column upper edge beam and the B column lower edge beam are subjected to laser tailor welding; a fourth welding seam is formed after the B column lower edge beam and the A column lower edge beam are subjected to laser tailor welding; wherein the A-column roof side rail is made of a material with the tensile strength reaching 2000Mpa. According to the embodiment of the invention, the material with the tensile strength of 2000Mpa is applied to the A-pillar roof side rail, so that the A-pillar roof side rail is prevented from being bent in a 25% small offset collision process.

    本公开涉及车辆技术领域,具体涉及一种热成型门环、热成型门环加工方法及车辆。本公开提供的热成型门环包括A柱下边梁、A柱上边梁、B柱上边梁和B柱下边梁;所述A柱上边梁与所述A柱下边梁激光拼焊后形成第一焊缝,所述A柱上边梁与所述B柱上边梁激光拼焊后形成第二焊缝;所述B柱上边梁与所述B柱下边梁激光拼焊后形成第三焊缝;所述B柱下边梁与所述A柱下边梁激光拼焊后形成第四焊缝;其中,所述A柱上边梁由抗拉伸强度达到2000Mpa的材料制成。本公开实施例通过将抗拉伸强度达到2000Mpa的材料应用于A柱上边梁,避免25%小偏置碰撞过程中A柱上边梁发生折弯。
