Abstract
A method for bonding together a pair of members comprising positioning a layer of soldering glass between the pair of members, melting the glass, bonding the members into the molten glass and cooling the members. One of the members may be conductive with the soldering glass coated thereon, or the soldering glass may be coated on a conductive element which becomes bonded between the pair of members.
Claims10
A method for bonding two nonconductive members made of glass or ceramic material, one of which includes an element made of a heat-fragile substance, comprising interposing a metal member coated with soldering glass between the nonconductive members, said metal member being out of contact with at least the nonconductive member including the heat-fragile element, passing an electric current through the metal member to heat the same to a temperature which is higher than the temperature damaging to the heat-fragile element of the nonconductive member thereby to melt the soldering glass, pressing the metal and nonconductive members together with the molten soldering glass therebetween cooling these members before said heat-fragile element is heated by the heat resulting from the current passing through the metal member to such temperature that it is damaged or has its properties substantially deteriorated.
