stud bolt and nut for drawn arc stud welding

1. Applicable Scope of shear stud

(1) Nominal diameters: Φ10-25mm cheese head shear studs 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, JIS B 1198

3. Dimensions and mass of shear stud

Symbols and abbreviated terms

d = nominal diameter

d₁ = diameter of the weld collar

d_k =  head diameter of shear stud

k =  height of the head on shear stud

h =  height of the weld collar

l =overall length of the shear stud (excluding aluminium 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) d1 and 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 studs through metal deck. 3. The types of ceramic ferrules are at manufacturer's discretion.
