面縦シーム部の溶接装置。In a welding device for welding a longitudinal seam on the inner surface of a steel pipe, a guide roller that runs along the groove is provided at the front lower part of a boom that moves with one end supported by a trolley, and a welding head is installed behind it. A set of auxiliary rollers that can be moved circumferentially and longitudinally of the steel pipe performs the welding process.
A welding device for welding a longitudinal seam on an inner surface of a steel pipe, characterized in that it is installed so as to be able to rise and fall freely so as to come into contact with the inner surface of the steel pipe at the rear of the rad so as to straddle the weld line.
