Welding — Studs and ceramic ferrules for arc stud welding
International Standard
ISO 13918
Studs and Ceramic Ferrules for Arc Stud Welding is the technical standard for shear studs which specifies:
1-the requirements for studs and ceramic ferrules for arc stud welding;
2-dimensions, materials, mechanical properties and, when required, conditions of evaluation of conformity
SHEAR CONNECTION IN COMPOSITE BEAMS Shear Connector Studs are designed to tie the concrete slab to the
steel beams and to resist shear loadings between the concrete slab and steel beam in composite
construction. This enables us to load up to 1000 kg/m² instead of the usual load
which is much less. The procedure saves time and therefore money as well due to its simplicity.
Each weld cycle depends on the diameter of the fastener and the material being joined and takes
up to only 1 second. Welding currents range from
240 to 3000 amps. The Shear Stud is made of steel and it is delivered with
a ceramic ferrule to ensure a
good connection of the Stud with the beam.The shear Studs are available in different
lengths and diameters . The length of the Stud
will be reduced by approximately 5mm during the welding process. All Shear Studs are
supplied with ferrules. The ferrules are
made of clay and able to withstand heat shock as well as
high temperatures without melting or breaking.
The shear connection of
a composite beam comprises five elements that can all influence behaviour. They include
the shear stud connectors, profiled steel sheeting(steel deck) ,
slab reinforcement (rebar or steel mesh) , concrete
slab and steel beam top flange.
In such design the shear Stud connects the steel deck to the concrete slab.
Shear Stud Connectors are the most important element in Composite Beam design securing
the concrete to steel structural components. Shear Stus Connectors resist shear forces
and increase shear loading capacity in steel buildings,bridges,
Design of the shear stud connector is very important because
1- it affects the choice
of a suitable ultimate strength design method for the composite beam
2-The economics and speed of construction
3-The stability of the steel beam
4-The safety of steel beam against collapsing
The ultimate strength of most composite beams is governed by shear stud connector shear
capacity
High Quality Wire Rods are used in
manufacturing welding shear stud connectors to achieve high quality welding studs
We guarantee High Quality
welding stud manufacturing process including packaging until the welding stud connectors
reaches you in perfect condition.
WE
DON'T ONLY MANUFACTURE SHEAR STUD CONNECTORS
BUT WE ALSO USE OUR OWN WELD STUDS
IN OUR STUD
WELDING PROJECTS AND
USE ONLY "GROUP ENERGY"
SHEAR STUD CONNECTORS.
