The invention belongs to the technical field of titanium alloy machining, and particularly relates to a thin-wall large-length-diameter-ratio titanium alloy powerful hot spinning machining method which comprises the following specific steps that the thickness T0 and the length of a raw material are determined according to the diameter length L1 and the thickness T1 of a target required part, generally, the raw material is a thick-wall machining pipe fitting subjected to extrusion or forging, and the length of the raw material is T0; the roughness of the inner surface and the outer surface is 3.2 grade, the general diameter of the machining allowance is not smaller than 3 mm, the calculation principle is that the size is not changed, and the thickness is far smaller than the diameter, the problems that conventional flame heating is not uniform, the production efficiency is low and the control difficulty is large can be solved by combining the induction heating technology and the powerful spinning technology, t
