Title: Method and device for conducting remotecontrolled welding in the interior of pipe of steam generator particularly in nuclear power plant
Inventor: JIYATSUKU GURIFUATON
IPC: G21C17/003
Filed: 1989-10-13
Abstract: PURPOSE: To surely perform welding remotely inside a tube in the optimum convergent state by transmitting a low power beam through a transmitting optical fiber to a welding head equipped with an optical cell and adjusting the transmitting fiber on the basis of reflection light intensity. CONSTITUTION: An optical cell 5 is inserted through an extended part assembly 3, 4 into a bush M to be welded that is arranged inside a tube T. This optical cell 5 is rotated around an axis A by a motor 2. In addition, a welding beam from a welding laser isolated from the tube T and arranged is transmitted to the optical cell 5 through a transmitting optical fiber F. The bush M is thereby fillet-welded inside the tube T. In this welding method, before the projection of the welding beam, an adjustment beam is projected that has a lower power than the welding beam, the intensity of the return beam from the impact point is measured. The transmitting fiber F is advanced and retreated in the direction of the axial line A so that the intensity reaches the maximum value and/or a prescribed value. Consequently, the optimum position of the beam projection is found and determined.

Filed: 1988-10-25
Abstract: PURPOSE:To restrict a shortcircuit current at a low level by providing a current detecting means in a circuit for applying a current to an electrode of a DC are furnace, setting overcurrent detecting levels by this current detecting means in multiple stages, and changing a phase angle of a shifting pulse at a rectifier corresponding to each level.
