OMG Roofing offers a plate fastener that is induction welded to secure roofing membranes via an OMG RhinoBond welder. However, the OMG welder can be used with non-OMG branded plate fasteners. This poses a significant challenge for the company as a substantial portion of their profits relies exclusively on sales from the plates. The project aims to develop a process in which the welder can reliably identify OMG branded plates from competitor plates, even when separated by a half inch thick roofing membrane. This will be done via measuring its electrical properties during the weld. By adding a thin coating to the OMG plate, in combination with its proprietary composition, the plate's have a resistance reading that uniquely identifies them as OMG branded.
