Laser welding of glass components

With laser-based welding, flat glass and glass tubes can be joined on a largely automated basis. Not only glass-glass joints, but also glass-metal joints are possible.

The process for laser welding of glass components developed at the Laser Zentrum Hannover e.V. (LZH)  makes it possible to join borosilicate and quartz glass with the laser. To achieve a constant component quality, the surface temperature is measured and controlled during the process without contact, and thus the viscosity of the glass is decreased in a well-defined way. The process control enables an extensive automation of the laser-based glass welding process. If necessary, wire or powder filler material can be used for gap bridging.
