Ceramic Ferrules or Arc Shields:
All TRU-WELD studs are supplied with ceramic ferrules designed for use with the particular fastener ordered. Ferrules are specially designed of ball clay and talc, an excellent material to withstand heat shock as well as reasonably high temperatures without melting or breaking.
What does that mean?
In a nutshell, the ceramic ferrule is designed to keep the molten weld material in place throughout the stud welding process, as well as allow the welding gases to escape and helping to prevent oxidation. Each ferrule is specifically configured for the application at hand, and will create the "fillet" around the welded stud that the inspector will be looking at before signing off on your project.
