PURPOSE: A tube fixing apparatus is provided to prevent a cross fire tube or an object to be welded from being deformed due to a welding heat source by fixing the cross fire tube to the object to be welded. CONSTITUTION: A tube fixing apparatus includes a base(10) installed on a ground, a turn table(20) rotatably positioned at an upper portion of the base(10), clamping plates(31,32) fixed to an upper surface of the turn table(20), a screw(40) vertically coupled to a center of the turn table(20), a pressing plate(50) surrounding the screw(40), and a nut(60) positioned at an upper portion of the pressing plate(50) and screw-coupled to the screw(40). The base(10) has a circular plate shape having a predetermined thickness. A hole is formed at the center of an upper surface of the base(10) in order to receive a ball bearing therein. Two-stepped perforation holes are formed at the center of the turn table(20).
