1. A method of securing a plurality of plates together to form a structure, the method comprising the steps of:
(a) securing at least two of the plates together to produce an intermediate segment of the structure having an initial opening therein, the intermediate segment comprising at least one opening wall at least partially around the initial opening, said at least one opening wall having at least one opening wall surface thereof partially defining the initial opening;
(b) providing an insert metallically bondable with the intermediate segment, the insert being formed to at least partially fit into the initial opening, the insert having an insert engagement surface formed for engagement with said at least one opening wall surface;
(c) positioning at least one heating element in a predetermined position relative to the insert engagement surface and to said at least one opening wall surface;
(d) providing a non-oxidizing atmosphere covering the insert, said at least one heating element, and the intermediate segment;
(e) energizing said at least one heating element;
(f) with said at least one energized heating element, in the non-oxidizing atmosphere, heating an intermediate segment heated portion to a hot working temperature, the intermediate segment heated portion extending from said at least one opening wall surface into the intermediate segment, said intermediate segment heated portion being plastically deformable at the hot working temperature;
(g) with said at least one energized heating element, in the non-oxidizing atmosphere, heating an insert heated portion extending from the insert engagement surface into the insert to the hot working temperature, said insert heated portion being plastically deformable at the hot working temperature;
(h) while the intermediate segment heated portion and the insert heated portion are at the hot working temperature, subjecting the insert to an insert engagement motion, to move the insert engagement surface relative to the opening wall surface;
(i) while the insert is subject to the engagement motion, and while said insert heated portion and said intermediate segment heated portion are at the hot working temperature, subjecting the insert to a translocation motion to push the insert at least partially into said initial opening;
(j) while the insert is subject to the engagement motion, and while said insert heated portion and said intermediate segment heated portion are at the hot working temperature, pressing the insert engagement surface against said at least one opening wall surface to cause plastic deformation of said intermediate segment heated portion and of said insert heated portion, for creating a metallic bond between the insert and the intermediate segment; and
(k) allowing the insert and the intermediate segment to cool, to bond the insert and the intermediate segment together.
