Title: INDUCTION-HEATING WELDING METHOD FOR VACUUM GLASS
Abstract:
An induction-heating welding method for vacuum glass. The vacuum glass comprises an upper glass substrate and a lower glass substrate. Meta layers are prepared in regions to be sealed of the upper glass substrate and the lower glass substrate. A continuous solder is distributed on the metal layer in the region to be sealed of the lower glass substrate. The upper glass substrate and the lower glass substrate are superposed. During welding, the center of a high-frequency induction welding head moves forward along the center line of the width direction of the metal layers; during induction heating of corner regions of the metal layers, the position of a moving trajectory of the center of the high-frequency induction welding head relative to the center line of the width direction of each metal layer is changed, so that the moving trajectory of the center of the high-frequency induction welding head deviates from the center line of the width direction of the metal layers, and thus, induction power of the metal layers in the corner regions are reduced, and overheating of the metal layers in the corner regions is avoided.
