Abstract

Method comprises inserting a piece of metal in the shape of a closed loop between the zones and heating by some method to which the glass is insensitive, e.g. HF induction, the piece of metal being an individual piece and is exposed directly to the regions to be joined. Used for welding glass tubes, of the same or different diameters. Tubes may be butt welded if of the same dia. or welded one inside the other if of different dia. with either the outer or the inner tube terminating in a flange. The volume of glass actually brought to the melting point is limited to that volume strictly necessary to carry out the weld. Consequently, the shape of the glass close to the weld can remain unchanged, the heating time can be accurately controlled, and since the shape is accurately controlled, the shape of the weld can be controlled. Automatic processing is thus facilitated.
