Cheese Head Studs for Arc Stud Welding GB/T 10433

GB/T 10433 specifies the dimensional and technical requirements for cheese head studs designed specifically for arc stud welding applications . As a specialized fastener type, these studs feature a cylindrical head profile and are manufactured from low-carbon steel grades such as ML15, ML15AL, or SWRCH15A to ensure optimal weldability . The standard, which non-equivalently adopts ISO 13918:1998, covers studs with nominal diameters ranging from 10 mm to 25 mm and pre-weld lengths from 50 mm to 300 mm . These studs achieve tensile strengths of 400-550 MPa with minimum yield strength of 240 MPa, verified through specified tensile and bend testing procedures . They serve as critical shear connectors and anchorage components in composite steel-concrete structures .

Key Specifications
The standard defines critical dimensions including head diameter and height, stud diameter, and overall length with specified tolerances . Material specifications require cold-heading quality steel with controlled chemical composition to ensure consistent welding performance . Mechanical property verification includes tensile testing of machined specimens and bend testing (often using a套管) to validate ductility and weld integrity . Ceramic ferrule dimensions and types (B1 and B2) are specified in the appendices as integral components for shielding the welding arc .

Primary Design Rationale
The cheese head profile provides an enlarged bearing surface for load distribution after welding, essential for composite action in steel-concrete construction . The stud design prioritizes weldability through controlled material chemistry and dimensional precision at the welding base. The cylindrical geometry facilitates automated feeding in stud welding equipment while ensuring consistent arc initiation and fusion zone formation .

Application Profile
These studs are fundamental components in composite steel structures including high-rise buildings, bridges, industrial facilities, and infrastructure projects . They function as shear connectors in steel-concrete composite beams, anchorage devices in concrete embedments, and load-transfer elements in steel framing systems . Installation requires dedicated arc stud welding equipment with matched ceramic ferrule protection, following qualified welding procedure specifications verified through pre-production testing.
