Disclosed is a laser welding apparatus which is capable of improving the quality of a welding part by changing a welding condition in real time by sensing a welding line, which is minutely changed, in advance by using a seam tracker. The present invention provides a laser welding apparatus comprising: an oscillator for generating a laser beam; a head for irradiating a welding part with a laser beam by receiving the laser beam generated in the oscillator; a seam tracker for sensing the state of a welding line preceding in the front of the head; and a control part for controlling the oscillator by receiving a sensing result of the seam tracker.
