  • Process for welding glass so that metallic elements pass through the weld bead
    Patent number: 4142881
    Abstract: A process for welding two glass members together to form a weld bead through which connecting wires extend. The glass members are first brought into intimate contact with metal parts which can be heated by a high frequency current. The glass members are held close to one another with the wires disposed in the space between them, and the glass is then melted until it welds by heating the metal parts with the aid of high-frequency heating coil windings surrounding the metal parts.
