 Shear stud   with  ceramic ferrule

1. Applicable Scope of shear stud

(1) Nominal diameters:10-25mm cheese head shear connectors with ceramic ferrules
for arc stud welding.

(2) Shear connectors are typically used in composite steel construction for holding concrete
 slabs to steel members to resist shear forces and increase shear loading capacity in steel
buildings, bridges, columns caissons, containment liners, etc.They also act as embedment
anchors on miscellaneous embedded plates, frames, angles, strip plates, attachments and
 
connections.

2. Normative references

ISO 13918, GB/T 1043

3. Dimensions and mass of shear stud


Symbols and abbreviated terms

d = nominal diameter

d1= diameter of the weld collar

dk = head diameter of shear connector

k =height of the head on shear connector h = height of the weld collar

l =overall length of the shear connector (excluding aluminum ball or welding tip) l = l1+WA

l1= nominal length of the stud


  WA = length of fluxing A = shape A of tip

B = shape B of tip

1 = optional groove at manufacturer 's discretion

2 = optional arc welding tip at manufacturer's discretion α = face angle

(1) d1and h is the guide value. For special conditions, e.g. through-deck stud welding, they will be different.

(2) l1 is the design value. For special conditions, e.g. through-deck stud welding, l1 will be shorter.

(3) Due to the tolerances, the values of mass are only approximate.

Key

1. B1 type ceramic ferrules are mainly used for general downward welding as well as welding M13mm and M16mm shear studs through metal deck.

2. B2 type ceramic ferrules are only used for welding M19mm shear connectors through metal deck.

3. The types of ceramic ferrules are at manufacturer's discretion.
