<P>PROBLEM TO BE SOLVED: To provide a glass welding method for producing a welded glass article requiring airtight welding and a glass layer fixing method for the welding method. <P>SOLUTION: A glass layer 3 is irradiated with a laser beam L2 for calcination to fix the glass layer 3 to a glass member 4 by gasifying a binder and melting the glass layer 3. The irradiation area of the laser beam L2 has an area A1 and an area A2 arranged along an extending direction of a planned welding area R and is moved along the planned welding area R in a manner to move the area A1 ahead of the area A2. The area A2 of the laser beam is irradiated to the glass layer 3 before solidifying the glass layer 3 melted by irradiation of the area A1. Accordingly, the time necessary for solidifying the glass layer 3 is prolonged to make easy the escape of the binder gasified by the irradiation of the area A1 of the laser beam L2 from the glass layer 3. <P>COPYRIGHT: (C)2011,JPO&INPIT |
