Honeycomb welding is typically used in aerospace applications or in turbine applications where a metal honeycomb structure brazed into an engine housing or a turbine housing, providing a tight seal between the engine/turbine housing and the rotor blades.
The honeycomb structure is tack welded into position on the housing before the entire housing is placed into a vacuum oven for vacuum brazing.
For this application a high-power capacitive discharge welder is ideal accompanied by a honeycomb electrode. The capacitive discharge welder delivers very high currents in a very short period of time, enabling a tack weld to take place without burning the very thin honeycomb structure.
In order to evenly distribute the current over a relatively large area of honeycomb, high force head is required along with a honey comb electrode.
