stud bolt standard size for drawn arc stud welding
stud bolt standard size for drawn arc stud welding
1. Applicable Scope of stud bolt
(1) Nominal diameters: Φ10-25mm cheese head stud bolts 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 stud bolt
Symbols and abbreviated terms
d = nominal diameter
d1 = diameter of the weld collar
dk = head diameter of stud bolt
k = height of the head on stud bolt
h = height of the weld collar
l =overall length of the stud bolt (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

(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. | |||||||
