- 두 장의 철판을 프레스로 각각 "ㄷ"자 형태로 절곡한 다음 서로 마주보게 겹쳐서 바(bar) 형태의 파이프(10)를 형성하되, 파이프(100)의 양측 및 중간에 프레스 작업으로 통공(14)을 뚫고, 겹쳐진 부분을 따라 간격을 두고 용접하여 간헐용접부(13)를 형성하는 제1 단계와;
상기 파이프(10)에 대하여 직각을 이루는 방향으로 파이프(100)의 양단에 위치하고 상면 중앙부에 와셔A,B(20a)(30a)를 갖는 한 쌍의 부싱A,B(20)(30)를 구비하는 제2 단계와;
상기 각각의 부싱A,B(20)(30)를 파이프(100)의 양단에 일체로 용접하되, 맞닿는 면적을 확대하기 위해 용접 전에 파이프(100)의 양단을 부싱A,B(20)(30)의 형상을 따라 원호형으로 따내기 한 후 용접하는 제3 단계와;
상기 제3 단계의 부싱A,B(20)(30)이 양단에 용접된 파이프(100)를 전착 도장한 후 건조시키는 제4 단계;로 이루어진 것을 특징으로 한 NVH 및 R&H 향상을 위한 차량용 언더바의 제조방법.
