Ceramic ferrules are specially-designed ceramic rings used in arc stud welding to contain the molten metal, control arc stability, and form a clean and strong weld fillet.
They are typically made from high-grade cordierite ceramic, offering excellent heat resistance, mechanical strength, and dimensional stability.
Ceramic ferrules are essential consumables in shear connector welding, construction steel structures, bridges, shipbuilding, prefabrication workshops, and industrial fabrication.
Ceramic ferrules are widely used in many industries that perform ARC stud welding:
Steel structure buildings
Composite beam & deck welding
Shear stud connectors (SDC)
High-rise building flooring systems
Highway bridges
Railway bridges
Orthotropic steel decks
Expansion joint structures
Ship deck stiffeners
Bulkhead structures
Container ships & offshore platforms
Pressure vessels
Boilers
Storage tanks
Prefabricated steel components
Power plants
Wind tower segments
LNG storage units
Ceramic ferrules produced by our factory have been widely applied in major projects:
Hong Kong–Zhuhai–Macau Bridge – Used for large-diameter shear stud welding on steel decks.
Singapore Offshore Oil Platform Fabrication – Provided for stud welding in high-temperature marine environments.
United States Highway Bridge Rehabilitation Project – Ensured consistent weld fillets and minimized welding defects.
High-Rise Steel Structure Buildings in Dubai & Qatar – Applied in composite beam systems with thousands of studs welded per site.
You can replace these with your own cases if needed.
