Title:
METHOD AND DEVICE FOR MANUFACTURING SPACE GRATING OF REACTOR THROUGH PULSE LASER WELDING
Document Type and Number:
Japanese Patent JPS58159992
Kind Code:
A
Abstract:
The present invention relates to a method and to an apparatus for producing nuclear reactor structures, such as spacing grids, by pulse laser welding. The grid is placed in a tight enclosure and having thin plates, which intersect one another, so as to define a certain number of crosspieces. By means of a laser source positioned externally of the enclosure, each of the ends of the crosspieces is fixed and optionally the crosspieces are welded along the intersections of the plates. Application to the construction of zirconium alloy spacing grids.
