Abstract

PURPOSE: To perform welding without necessitating welding repair by detecting the groove gap quantity, the groove dislocation quantity and the groove central position by the change of the voltage obtained by traversing a laser displacement sensor on the groove face.
CONSTITUTION: The groove gap quantity G and the groove dislocation quantity H exist in a groove 2 of a butt joint of an iron pipe 1 to by subjected to one- side welding. A welding carriage 4 supporting a welding torch 3 in opposition to the groove 2 travels along a weld line one the pipe interior. A rear side carriage 6 provided with backing material 5 travels in synchronization with the welding carriage 4 on the pipe exterior side. The laser displacement sensor 8 is fitted and traversed on an X axis traverse shaft 9 to cross the groove rear 2a at the position opposite to the rear 2a of the groove 2 on the rear side carriage 6. The sensor 8 outputs the voltage in proportion to the distance L with the groove rear 2. This is converted into the groove gap quantity, the groove dislocation quantity and the groove central position and control is carried out by a rear side controller 12 and a welding controller 13 so that optimum welding is performed.
