Title:
COMPOUND METALLIC PLATE AND ITS PREPARATION
Document Type and Number:
Japanese Patent JPS5550934
Kind Code:
A
Abstract:
A panel includes metallic face sheets maintained in operative relationship with each other by a metallic core structure. The core structure consists of a plurality of securement core strips which may be internested or juxtaposed to provide a honeycomb core configuration. Structural integrity is created by the provision of internally generated welds which fasten securement portions of the core strips in operative relationship with the face sheets, but which can be terminated inwardly of the outer surfaces of the face sheets resulting in a very small volume of face sheet material being cast into a weld nugget and being heat affected and maintaining the integrity of the face sheets while, nevertheless, providing maximum structural strength and eliminating face sheet thickness limitations. Also disclosed is a method of fabricating the metallic panel which includes the steps of internally generating the weldments so that, by minimum pressure and minimum energy, discrete welds are formed which fasten the securement portions of the core strips in operative relationship with the face sheets while greatly reducing the dimensions of the weld nuggets in comparison with the nuggets which result from the utilization of prior art external welding techniques.
