The present invention relates to a welding method for a quartz glass plate which makes quartz glasses to be welded to face each other, fixes the quartz glasses and welds the quartz glasses by heating the quartz glasses with welding flame. The welding method for a quartz glass plate installs the quartz glasses on a welding apparatus; heats the welding part of the quartz glasses in a state where quartz glasses are separated; closely attaches the quartz glasses by completing a welding operation; maintains a gap between the quartz glasses by pulling the quartz glasses back at a constant distance; cools the heat in a state where quartz glass melt exists between the maintained gap; and performs a polishing process, thereby being able to strengthening the welding part of the quartz glasses and preventing the welding part from being optically stained. Additionally, the welding method for a quartz glass plate is able to adjust an angle of the welding apparatus for welding quartz glasses, thereby strengthening the efficiency of the welding apparatus. |
