PURPOSE: A fixing apparatus for preventing welding deformation is provided to lower the temperature of a part close to a welding spot by locating water-cooling plates in the part. CONSTITUTION: A fixing apparatus for preventing welding deformation comprises a flat bottom support plate(50), first and second fixing plates(11,12), a cooling channel, a flow pipe, a supply pipe(21), a delivery pipe(22), and a discharge pipe(23). The bottom support plate is provided on the underside of a welding unit moving along a guide rail. The first and second fixing plates are erected on the top of the bottom support plate and extended along the guide rail. The cooling channel is formed along the guide rail inside the first and second fixing plates. The flow pipe is provided in the cooling channel. The supply pipe supplies cooling water to the first fixing plate. The delivery pipe transfers cooling water from the fist fixing plate to the second fixing plate. The discharge pipe discharges cooling water from the second fixing plate. The first fixing plate is coupled to the bottom support plate and, the second fixing plate is movable coupled to the bottom support plate. The flow pipe is integrally connected to the supply pipe, the delivery pipe, and the discharge pipe to form a single pipeline.
