19×125 Stud Weld Stud: Maximum Connection Strength for Deep Concrete Structures
The 19×125 stud weld stud is a heavy-duty fastening element manufactured with a 19 mm diameter and 125 mm length, designed for welding onto steel surfaces using the stud welding process. It is particularly suitable for deep concrete slabs, high-load-bearing structures, and composite construction systems.
Its extended shank provides excellent mechanical interlock with concrete, delivering outstanding tensile and shear resistance for demanding structural applications.

Installation Information
The 19×125 stud weld stud is fixed vertically onto a steel surface using a stud welding gun and a ceramic ferrule. During the welding process, a high electrical current melts the base of the stud and the steel substrate, creating a strong metallurgical bond.
The ceramic ferrule protects the weld area and helps form a consistent weld pool. After welding, the surface is cleaned and concrete placement can begin, ensuring maximum anchorage and structural performance.
Frequently Asked Questions (FAQ)
1. What are the advantages of the 125 mm length?
It provides greater embedment depth in thick concrete sections, increasing bond strength and overall connection performance.
2. Where is it most commonly used?
It is ideal for heavily loaded floor systems, thick concrete decks, industrial platforms, and large-scale structural projects.
3. What welding equipment should be used?
Installation should be carried out using automatic stud welding machines compliant with EN ISO 14555 standards.
4. When can concrete be poured after welding?
Concrete placement can begin immediately after the welding operation is completed and the surface has been properly cleaned.
