Unthreaded Stud Welding

Threaded stud welding (It is also called PD type)are typically used in composite steel construction to tie the concrete to steel members and resist shear forces between the concrete slab and steel members. Plenty of steel construction(such as steel building, steel beam, steel bridges, etc.) uses threaded stud widely.

There are two welding ways to connect threaded stud and steel plate, one is welding directly, which need the normal ceramic ferrule with multi-teeth(about 18 teeth or 21 teeth), the other is welding through metal deck, for this option, it is recommended to use special ceramic ferrule thru-deck type(8 teeth).
