The present invention relates to a welding deformation prevention apparatus for an underframe base panel for a railway vehicle and, more specifically, to a welding deformation prevention apparatus for an underframe base panel for a railway vehicle which prevents welding heat of a lower portion from being transferred to an upper portion to improve quality. The welding deformation prevention apparatus for an underframe base panel for a railway vehicle comprises: a chamber formed in a rectangular box shape of which the upper surface is opened to play a role of storing cooling water sprayed to the underframe to drop, and provided with a drain line formed on a bottom portion thereof to discharge used cooling water; and a cooling means formed on the chamber to include a cooling water moving pipe and a plurality of cooling nozzles formed on the cooling water moving pipe to cool welding heat generated when welding a lower structure on the underframe.

    본 발명은 철도차량용 언더프레임 베이스 판넬 용접 변형 방지장치에 관한 것으로서, 특히 하부의 용접열이 상부로 전달되는 것을 방지하여 품질을 향상하는 철도차량용 언더프레임 베이스 판넬 용접 변형 방지장치에 관한 것이다. 구성은 철도차량용 언더프레임 베이스 판넬 용접 변형 방지장치에 있어서, 언더프레임에 분사하여 떨어지는 냉각수를 가두는 역할을 하도록 상면이 개방된 직사각형의 박스 형태로 이루어지며, 바닥 부분에는 사용된 냉각수를 배출하기 위한 배수라인이 형성되는 챔버와; 상기 챔버에 형성되어 언더프레임에 하부 구조물의 용접시 발생하는 용접열을 냉각하도록 냉각수 이동 파이프와 상기 냉각수 이동 파이프에 형성되는 복수 개의 냉각 노즐로 이루어지는 냉각수단; 을 포함한다.
