A welding pressure control system includes: an anvil on which a welding subject is supported; a horn that presses the welding subject; an elevating unit that supports the horn to be ascendable and descendable; a sensing unit that senses a pressure value varying depending on the ascent and the descent of the horn; and a control unit that controls the elevating unit based on the pressure value obtained from the sensing unit. The elevating unit includes a motor, a screw that receives driving power from a rotary axis of the motor and rotates, a vertically movable part that is coupled to the screw and moves vertically during the rotation of the screw, and a support that is coupled to the vertically movable part and supports the horn. The sensor is disposed circumferentially about the screw and pressed according to the vertical movement of the vertically movable part.
