Glass welding method and device

The invention discloses a glass welding method and device. The method comprises the following steps that glass is placed, specifically, two pieces of glass are stacked, and a plurality of pressing tools are arranged in the circumferential direction of the glass; the clamping areas of the two pieces of glass are pressed through a plurality of pressing tools; gap detection: detecting a gap between the two pieces of glass along the circumferential direction of the glass and generating gap distribution information; gap judgment: judging whether the gap distribution information meets a welding gap requirement or not; if not, the pressing degrees of the multiple pressing tools are adjusted according to the gap distribution information, and the gap detection step and the gap judgment step are repeated till the gap distribution information meets the welding gap requirement; if yes, welding the welding areas of the two pieces of glass in the circumferential direction of the glass. According to the glass welding device
