PURPOSE: A welding apparatus for controlling a pressure power of a welded object is provided to catch an inclined state of a servo gun through a gradient sensor by mounting the gradient sensor on the servo gun of the welding apparatus. CONSTITUTION: A welding apparatus for controlling a pressure power of a welded object includes a servo gun formed with a first gradient sensor(110a) and a second gradient sensor(110b) in order to perform welding work while applying a pressure power to the welded object. A robot is provided with the servo gun and changes a position and a posture of the servo gun according to a size and a position of the welded object. A controller receives data related to a gradient of the servo gun from the first gradient sensor(110a) and the second gradient sensor(110b).
