The present invention relates to a manufacturing method for a lightweight two-piece wheel, comprising: a step for manufacturing a disc unit casting to manufacture a disc unit with spokes formed in between a hub and a flange with the same interval through casting and a first bonding unit for bonding with a rim unit at the bottom; a step for manufacturing a rim unit to manufacture a rim unit with a second bonding unit on the top through casting; a step for flow forming of the rim unit to perform flow forming of the rim unit and to perform shape processing of the rim unit; a step for forming a resonance hole to form multiple resonance holes on the second bonding unit of the rim unit; and a step for stirring and bonding with friction to settle the disc unit on the top of the rim unit to form a space in the shape of a ring connected to the resonance holes in between the first bonding unit and the second bonding unit and to perform stirring and bonding with friction of the parts where the disc unit and the rim unit come in contact with each other by using a tool for stirring and bonding with friction.

    본 발명은 경량화 구현을 위한 투피스 휠 제조방법에 관한 것으로, 주조를 통해 허브와 플랜지 사이에 스포크가 등 간격으로 형성되며, 하부에는 림부와 접합을 이루는 제1접합부를 구성한 디스크부를 제작하는 디스크부 주물제작단계; 주조를 통해 상부에 제2접합부가 구성된 림부를 제작하는 림부 주물제작단계; 상기 림부를 플로우포밍하여 림부의 형상가공을 이루는 림부 플로우포밍단계; 상기 림부의 제2접합부에 복수 개의 공명홀을 형성하는 공명홀 형성단계; 상기 제1, 2접합부 사이에 공명홀과 연통되는 링 형상의 공간이 형성되도록 디스크부를 림부의 상부에 안착시킨 후, 마찰교반접합공구를 이용하여 상기 디스크부와 림부가 서로 맞닿은 부분을 마찰교반접합 시키는 마찰교반접합단계;로 이루어진 것에 특징이 있다.
