Cordierite Ceramics

Cordierite Ceramic Ring of Welding Bolt

Our arc shields, or ferrules, are made from a cordierite composite material. Cordierite's properties make it an ideal material for stud welding. Cordierite exhibits low thermal expansion and low thermal shock. Our ferrules instantly heat up from ambient to welding temperature while effectively preventing cracking or explosion. Stud welding requires ferrules to concentrate heat and hold the molten metal at the base of the stud until it cools. After cooling, the ferrule breaks off, revealing the weld. The weld is actually stronger than the stud itself. Ferrules are required for most common stud welding applications.

Installation and Use:

Setup: Place the ceramic ferrule over the weld area, surrounding the stud.

Welding: At the beginning of welding, the ferrule helps shape the molten metal and protect the weld pool.

Post-Welding: After welding, the ferrule is typically broken off and removed, revealing the finished weld.
