The invention provides a self-incremental spinning thermal mechanical coupling synchronous forming device and method for a titanium-containing laminated composite tube. The self-incremental spinning thermal mechanical coupling synchronous forming device comprises a titanium tube blank, a titanium tube blank fixing device, a machining tool group, a self-resistance heating tool and a spinning forming device. The self-resistance heating tool comprises a high-frequency low-voltage power supply, a carbon brush holder assembly, a carbon brush rod, a magnetic fixing frame and a wire, wherein one endof the carbon brush rod is in interference fit with the carbon brush holder assembly through insulating treatment, and the other end of the carbon brush rod is fixed to the magnetic fixing frame in ascrew thread fit mode. The magnetic fixing frame is fixed to a moving tip. The positive pole of the high-frequency low-voltage power supply is connected with the carbon brush holder assembly through the wire, and the negative pole of the high-frequency low-voltage power supply is connected with a binding post of a spinning wheel. The high-frequency low-voltage power supply, the titanium tube blank, the spinning wheel, a tail top, the wire and the carbon brush holder assembly constitute a current loop. According to the self-incremental spinning thermal mechanical coupling synchronous forming device and method for the titanium-containing laminated composite tube, the prepared titanium-containing laminated composite tube is subjected to thermal mechanical coupling spinning, the bonding strength between the inner and outer pipe interfaces is large, and no cracking occurs.
