PURPOSE: A pile automatic welding apparatus capable of being easily assembled and disassembled, and a pile welding method using the same are provided to weld piles without dislocation and to level the apparatus, thereby preventing failures in welding. CONSTITUTION: A pile automatic welding apparatus (10) capable of being easily assembled and disassembled includes a rail unit (20), a revolving conveyor (30), a welding torch holder (40), and a centering band (50). The centering band simultaneously sets the leveling of the rail unit and centers the welding portions of an upper pile and a lower pile. The rail unit at the outer diameter of the pile guides the movement of the revolving conveyor into the revolution of the rotating conveyor. The rotating conveyor is detachably installed at the rail unit, and revolves along the circumference of the upper pile. The welding torch holder is detachably connected to the revolving conveyor, and supports a welding torch.
