The invention relates to a convex vacuum glass having installing holes by metal welding at sealed edge of a sealing strip, which comprises an upper glass and a lower glass, the installing holes are provided, 1-4 installing holes are provided, at least a sealing strip is respectively provided at circumference of the upper glass and the installing hole, at least two sealing strips are provided at circumference of the lower glass, at least a sealing strip is arranged at the lower glass corresponding to the installing hole, the sealing strip of the upper glass is inserted between 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 a metal solder in a 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 usage life is increased.
