Ceramic Ferrule For Stud Welding

Product Details

UF Ceramic Ferrules

Place of Origin: China (Mainland) 

Type: Ceramic ferrule for shear stud welding 

Standard: BS EN ISO 13918, type UF, welded shear connector for steel, with direct memory 

Model: UF13, UF16, UF19, UF22, UF25 

Brand name: Global ceramic ferrules


The ceramic ferrule is an indispensable part in the welding process of the shear stud of the connector.

It has the following functions:

◇Protect the welding pool by generating metal vapor with sufficient current intensity in the combustion chamber;

◇The arc is concentrated and stable, reducing the arc blowout;

◇Form the replaced weld pool to the welding ring and support the weld pool. In addition, it protects the operator from arcs and splashes. The ceramic ferrule is only used for one time welding, and once the molten metal solidifies, it is removed. The integral ceramic ferrule with high-precision size and low water absorption rate can significantly improve the welding effect.

Specifications

1. Applicable Scope of bolt and nut

(1) Nominal diameters: Φ10-25mm cheese head perfobond shear connector for composite constructions 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, AWS D1.1, BS 5400

(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 perfobond shear connector for composite constructions through metal deck.
     2. B2 type ceramic ferrules are only used for welding M19mm perfobond shear connector for composite constructions through metal deck.
     3. The types of ceramic ferrules are at manufacturer's discretion.

Arc Shields (Ferrules)

Our arc shield or ferrule is made of cordierite material. Cordierite has properties that make it very suitable for stud welding. Cordierite has low thermal expansion and low thermal shock. Our Ferrules can instantly rise from the ambient temperature to the welding temperature, and can prevent cracking or explosion. Stud welding requires the use of ferrules to concentrate heat and retain molten metal at the bottom of the stud until it cools. After cooling, the ferrule is broken to expose the weld. In fact, the welding strength is ultimately stronger than the stud itself. In most applications where stud welding is prevalent, sealing washers are required. The most common applications are bridge and road maintenance and the construction of buildings and skyscrapers.
