CEN/TC 121/WG 16 - Welding of reinfocing steels

ISO 17660-1:2006 is applicable to the welding of weldable reinforcing steel and stainless reinforcing steel of load-bearing joints, in workshops or on site. It specifies requirements for materials, design and execution of welded joints, welding personnel, quality requirements, examination and testing.
ISO 17660-1:2006 also covers welded joints between reinforcing steel bars and other steel components, such as connection devices and insert anchors, including prefabricated assemblies. Non load-bearing joints are covered by ISO 17660-2.
ISO 17660-1:2006 is not applicable to factory production of welding fabric and lattice girders using multiple spot welding machines or multiple projection welding machines.
The requirements of ISO 17660-1:2006 are only applicable to static loaded structures.

ISO 17660-2:2006 is applicable to the welding of weldable reinforcing steel and stainless reinforcing steel of non load-bearing welded joints, in workshops or on site. It specifies requirements for materials, design and execution of welded joints, welding personnel, quality requirements, examination and testing.
Load-bearing welded joints are covered by ISO 17660-1.

This Technical Report presents a method to verify the  tack weldability of reinforcing steel. The purpose is to ensure that sufficient strength and ductility will remain in the welded material when short welding times are applied. This Technical Report does not cover the welded joint itself.

This standard applies to the welding of weldable reinforcing steels and stainless reinforcing steels according to relevant standards or technical qualifications in workshops or on site. It covers also joints between reinforcing steel bars and other steel components such as connection devices, insert anchors including prefabrica-ted assemblies.
This standard does not apply to factory production for welding fabric and lattice girders.
The requirements of this standard only apply for static loaded structures. This standard specifies requirements for materials, design and execution of welded joints, welding personnel, quality requirements, examination and testing.
