Method for additive manufacturing of titanium-aluminum alloy through high-frequency induction hot wire GTA

The invention discloses a high-frequency induction hot wire GTA additive manufacturing method for a titanium-aluminum alloy, and belongs to the technical field of additive manufacturing. According to the method, the titanium welding wires are preheated to a certain temperature before being fed into the electric arc by adjusting the technological parameters such as the wire feeding speed, the scanning speed, the welding current and the high-frequency induction heating power, it is guaranteed that the two welding wires can be synchronously and continuously melted under the heating of the same electric arc, and the titanium-aluminum alloy component with the uniform component structure is obtained. By means of the method, the problem that heterogeneous twin-wire melting is not synchronous when intermetallic compounds are manufactured through GTA additive manufacturing at present is effectively solved, the stability of the manufacturing process is improved, the technological parameter interval ...
