Abstract:
A method for interlocking structural steel components with a metal-filled interlock is disclosed herein. The method comprises placing a mold about aligned contoured portions of structural steel components and attaching a crucible and a spout to the mold. The crucible is charged with exothermic reactive metals which are ignited, forming a molten metal filler. The molten metal filler melts a metal plug in the crucible or spout and the molten metal filler flows into the mold and about the aligned contoured portions of the structural steel components. Cooling of the molten metal filler forms a metal-filled interlock. Molds for performing the disclosed method are also disclosed herein.
