| Abstract: | The paper aims to develop a water cooling system for the tools to solve the problem of severe wear of the tools during the friction stir welding of titanium alloy. The water cooling system mainly consists of five parts: a rotating shaft, a protective cover, a cooling water circulation device, a cooling water pipe, and a directional hood. The device has the advantages of simple structure, convenient operation and reliable clamping. After welding for 0.5 m, the tools was almost wear-free, the wear condition of the tools was improved. Good connection of the titanium alloy was achieved. The maximum hardness of the stir zone of joint reached HV527. With the water cooling system for the welding tools, the wear of the tools can be reduced, and the joint quality and welding efficiency can be greatly improved. |
