Abstract

PURPOSE: To efficiently, spirally build-up weld over entire length of inner face of the pipe, by adjusting the rotational speed of the pipe and the traveling speed of the welding torch so as to form the spiral bead at an interval, and by build-up welding the space in the interval after removing the slag.
CONSTITUTION: The pipe 5 is rotated by the driving roller 3, and the wire 28 is led to the welding torch 23, and then, the welding is started; at the same time, the welding bench 22 is moved backward by the traveling driver 20. The state of this buil-up welding is monitored by the television camera 26. The spiral buil-up is formed at an interval narrower than the width of bead over entire length of inner face of the pipe 5, by adjusting the rotation of the pipe 5 and the traveling speed of the welding bench 22. Then, after the slag of this built-up bead is hemoved, the space in the interual is build-up welded according to the similar procedure and the entire circumference of inner face of the pipe 5 is build-up welded. According to this method, the time necessary for the build-up welding is shortened
