Product Description
Cylindrical head welded studs are high-strength fasteners secured to a metal base material using arc stud welding technology. As an indispensable and highly efficient connecting element in modern steel structure engineering, they are widely used in various construction and industrial sectors due to their outstanding mechanical properties and ease of installation, providing a reliable guarantee of structural safety.
Product Features
High-strength connections
The welding process creates a metallurgical bond, resulting in excellent shear and tensile strength, as well as high rigidity
Efficient installation
No drilling or tapping required; formed in a single welding operation, significantly reducing labour time
Extremely reliable
Consistent weld quality, uniform stress distribution and excellent seismic performance
Design flexibility
Suitable for connecting and anchoring a wide range of complex structures
Installation method
Arc stud welding: A mainstream process that utilises specialised stud welding machines in conjunction with ceramic rings to protect the weld seam.
Welding procedure:Cleaning of the base metal surface → Placement of the ceramic ring → Alignment of the stud → Arc initiation → Pressing down the stud → Power cut-off and cooling → Removal of the ceramic ring
Specialised processes: Penetration stud welding (used for composite floor slabs with profiled steel sheets) and energy-storage stud welding (used for thin-sheet connections)
application scenarios
Their primary function is to firmly bond steel members to concrete; they are mainly used in situations where steel and concrete must work together to bear loads, resist shear forces and withstand seismic activity. Typical applications include:
