[Scope of Claims] (In welding Mf& in which welding is performed while a welding torch is advanced along the route interval between 122 base metals, the echo level of each of the base metals is detected separately. A sonic probe is attached to the welding torch so as to be positioned one wound in front of the welding torch in the direction of travel, and each lateral signal from the ultrasonic probe is input so that the welding torch is positioned at the center of the root interval. The welding apparatus is characterized in that it is provided with a feedback control device that controls -fBj so that the The welding device according to claim (1), which is an electromagnetic ultrasonic probe equipped with a transmitting and receiving coil. (3) The welding torch is attached to an automatic bath welding machine or a welding robot, and the output from the feedback control device is The welding apparatus according to claim 1, wherein the automatic welding machine or the welding logo 1 is operated so that the welding torch 75 is at the center position of the root interval.
