Title: Process for welding plate glasses together

Abstract: The contacted edge portions of plate glasses to be joined are locally heated to a temperature higher than in the other portions of the plate glasses, after the whole of the plate glasses is heated. Electric current is then passed to the edge portions in order to further heat the edge portions so that the edges of the plate glasses are molten and welded together.
