The invention discloses a generator cooling water outlet aluminum pipe assembly. The generator cooling water outlet aluminum pipe assembly comprises a first flange, a first cooling water pipe, a second flange and a second cooling water pipe. The first flange is provided with at least one first through hole, and the second flange is provided with at least one second through hole. One end of each cooling water pipe is connected with the corresponding through hole in a welded manner, one side of the first through hole and one side of the second through hole are both provided with chamfers, and anannular space which can contain liquid welding flux is formed between each chamfer and the corresponding cooling water pipe. The periphery of the first flange and the periphery of the second flange are both provided with bolt holes, and bolts penetrate the bolt holes to fixedly connect the first flange with the second flange. In the process of welding the flanges and the cooling water pipes, theliquid welding flux is acc
