Tailor-layered tube with thickness deviations and method of manufacturing the same

A method of manufacturing a tailor-layered tube, the method comprising:

• inserting an inner tube into an outer tube and inserting an intermediate tube between the outer tube and the inner tube to align at a predetermined position, the intermediate tube having a length different from a length of the inner tube and a length of the outer tube;
• placing a laminate of the outer tube, the inner tube and the intermediate tube in a cavity of a mold;
• and
• supplying a fluid to an inside of the inner tube through one side portion of the cavity of the mold at a constant process pressure so that a pressure is applied to an inner peripheral surface of the inner tube, and simultaneously applying axial direction loads for axial feeding to both end portions of the laminate to perform a hydroforming operation, wherein, during the hydroforming operation, the inner tube, the intermediate tube, and the outer tube are hydroformed in a state of being laminated so that the inner tube, the intermediate tube, and the outer tube are sequentially brought into close contact with each other in a region where the intermediate tube is disposed and the inner tube is brought into direct contact with the outer tube in a region where the intermediate tube does not exist.
