Zusammenfassung:	PURPOSE: A method for manufacturing a valve seat of a valve is provided to form various shapes of valve seats and to manufacture a customized valve by the diversity of the valve seat. CONSTITUTION: A method for manufacturing a valve seat(100) of a valve is as follows: A valve shaft is installed in a fluid moving path of a valve body(10) in order to open and close the fluid moving path depending on the forward and backward rotation of a valve disc. A protruded line protrudes inwardly from the inner wall of the fluid moving path. Mold frames(600) are separately installed in both sides of the protruded line. Molten steel is injected in the protruded line and is thermally welded by a thermal welding machine(400). After forming a molten protruded part(300), the mold frame is removed. A processing machine(500) processes the molten protruded part to form a seat surface(140).
