Welded Stainless Steel Honeycomb Core for Aero Engine Seal is further fabricated from honeycomb core which are being used on aero engine. It is a necessary part for the modern turbine machinery. Based on the honeycomb structure, the working fluid overflow in the radial clearances is minimized, the relative efficiency be increased, fuel consumption be reduced by 5% and abrasive wear of the turbine flow section be reduced as well.


The honeycomb seal for gas turbine is an abradable seal part, which is used to seal the turbine and compressor parts of the gas turbine. During operation, the labyrinth is cut into the abradable honeycomb seal by abrasion, thereby reducing the gap level which other technical solutions are difficult to achieve. The amount of air leaking has been greatly lowered.
The performance improvement of using the honeycomb compound ring in the 2nd and 3rd stages of GE's new E-CLASS (61A/B) gas turbine:
Stage 2: output increases by 0.35%; heat ratio decreases by 0.35%
Stage 3: output increases by 0.25%; heat ratio decreases by 0.25%




1 Very low cross coupling
2 Higher direct damping that labyrinth seals
3 More forgiving than labyrinth seals in the event of a rotor-stator rub
4 Variety of materials available to serve a wide range of applications
5 Capable of sustaining higher temperatures than conventional labyrinth seals


Spot welding device is three electrodes in the upper part, which carries five welding points across the width of the strip of corrugated sheet metal. Spot welding device filled with press and advance mechanisms. There are five welders in every unit area to make sure the strength is enough and uniformly distributed based on electrodes welding of stack and resistance. The honeycomb core generally requires a good precision of welding process, high equipment control on the product and strict quality control during process. Stainless steel honeycomb is mainly for aerospace, high industrial application and civil areas, with the structure comprised of special foils (plates). Instead of general widely used adhesive bonding, stainless steel honeycomb is welded between those joint areas of the hexagonal shapes.


Welded honeycomb seals are an integral part which have to be used on existing aircraft engines and developing engines (turbofan, turboshaft engines and auxiliary power units). For the gas and steam turbines used in the power and oil/gas industries, as well as turbo-compressors should also be supported by this honeycomb seal.
