Arc Stud Welding Ceramic Ferrule RF UF PF Type
Key Features of Ceramic Ferrules:
- Material: Typically made from high-temperature resistant ceramics, such as alumina or zirconia.
- Shape: They come in various shapes and sizes, depending on the type of stud and application requirements.
- Durability: They are designed to withstand the high temperatures and mechanical stresses involved in welding.
- Disposable: Generally, ceramic ferrules are single-use items, discarded after each weld to ensure consistency and quality.
