automatic method and programmable to assiemaggio and welding of plates distanziatrici for elements of core of nuclear reactors and fast installation for its implementation.

摘要

The present invention relates to a method of assembling and welding distance plates to pipes with a polygonal base area, in particular to components of core elements of nuclear reactors, as well as a machine for carrying out the method. The method consists in the fact that the pipe is positioned by means of a chuck, that distance plates are positioned on the hexagonal pipe by means of a gripping device, and that the edges of the plates are tack-welded by positioning the welding torch, by first the long sides and then the short sides being welded on.
