The invention relates to a
metal-welded plain vacuum glass with installing holes and edge sealed by sealing strips, which comprises an upper glass and a lower glass, the installing holes and extraction openings are combined as an integral body, 1-4 installing holes are arranged, at least a sealing strip is provided at circumference of the upper glass and the extraction opening, at least two sealing strips are provided at circumference of the lower glass and the extraction opening, the sealing strip of the upper glass is inserted between the sealing strips of the lower glass; the upper glass and the lower glass are rapidly heated and laminated at high temperature, the circumference can be welded together by pressurizing through an
alloy solder in an
atmosphere heating furnace, and the extraction opening is enclosed by using
metal solder in
vacuum furnace. The vacuum glass and its production method have the advantages that the process is simple and the production efficiency is high, the prepared vacuum glass can eliminate the stress of the sealed edge and can keep the
toughening characteristic of the
toughened glass, so that toughened vacuum glass can be massively produced, and its usage life is increased.
