Described solder is coated on one or two face of weld periphery and the face of weld periphery of described sheet glass of upper and lower glass at least.

The formation of described single low dead level convex surface low latitude glass can adopt single stage method to form, and described single stage method comprises the steps:

With the even coating solder of one in the upper and lower glass or two face of weld periphery, evenly leave several grooves that pass through the eutectic welding strip or slit on the solder as production well; Upper and lower glass consistency from top to bottom is stacked together, sends in the high temperature edge sealing stove; Heating rises to more than the melt temperature of solder the interior temperature of stove, reaches the edge sealing temperature, and production well disappears; Stopped heating reduces furnace temperature to room temperature, and described solder welds together upper and lower glass is bubble-tight, thereby obtains needed convex surface low latitude glass.

It is as follows that the single stage method of described two low dead level convex surface low latitude glass forms step:

The periphery of upper convex glass, lower convex glass and middle sheet glass face of weld evenly is coated with solder, evenly leave several grooves that pass through the eutectic welding strip or slit on the solder as production well, and three glass consistencies from top to bottom are stacked together, send in the high temperature edge sealing stove; Heating makes that temperature rises to more than the melt temperature of solder in the stove, reaches the edge sealing temperature, and production well disappears, stopped heating, with the stove cooling, and solder hermetic welds together two blocks of glass, opens fire door and obtains required convex surface low latitude glass.

Described edge sealing temperature is preferably 150～550 ℃, further is preferably 290～350 ℃ when adopting low melting point metal or solder; When adopting low temperature glass solder, further be preferably 380～470 ℃.
