Abstract
The invention relates to a method for welding one end of a primary preform and one end of a silica bar having different properties. The method includes the steps of projecting and fusing silica grain under a plasma torch onto an end of the primary preform and an end of the silica bar, and bringing into contact these respective ends to form an excellent weld between the primary preform and the silica bar. The invention provides a cost-effective way to secure a primary preform to a glass-working lathe support while reducing the risk of costly preform breakage.
