The standard provides guidelines on the welding of cast irons. Cast irons are a group of ferrous materials that contain a high amount of carbon (typically more than 2%) and possibly other alloying elements. Due to their composition, welding cast iron presents specific challenges, such as the formation of hard, brittle phases and the potential for cracking.
Possessing the official document ensures you have the exact figures, tables, formulas, and tolerances required to successfully execute and audit load-bearing reinforcing steel welds.
A: Usually not. Scribd user uploads violate copyright law. If you use that document to create a WPS and a failure occurs, your insurance may be void because you did not use "current, authorized standards."
This standard covers load-bearing welded joints made with reinforcing steel bars and stainless reinforcing steel. It applies to bars with diameters ranging from small architectural elements to heavy structural reinforcement. Types of Welded Joints Covered
Before a WPS can be used in production, it must be qualified through a . The qualification workflow involves:
When the revised standard is finally published, it will supersede EN ISO 17660-1:2006. Organizations currently certified to the 2006 version should anticipate a transition period to update their welding procedures, personnel qualifications, and quality manuals to align with the new requirements.
To comply with EN ISO 17660-1, welders must pass a qualification test described in Annex A of the standard. This includes:
Not all rebar is weldable. The standard mandates that the base metal (the rebar) must possess suitable weldability.
EN ISO 17660-1:2006 is part of a family of standards for welding reinforcing steel. It is complemented by several important related documents.
Ensuring the tensile strength of the welded joint meets or exceeds the specified characteristic yield strength of the parent reinforcing bar. 3. Welder and Welding Operator Qualification
For many construction authorities, demonstrating compliance with is a mandatory part of the approval process. This is particularly important for contractors working on state-controlled projects, such as bridge construction, highway infrastructure, and high-rise buildings.
Note: Always ensure you are using the latest version of the standard. Conclusion

EN ISO 17660-1 classifies and regulates specific geometric configurations for load-bearing joints. Each configuration requires distinct preparation and welding parameters. 1. Butt Joints Used to connect bars end-to-end to extend their length.
EN ISO 17660-1 specifies requirements for materials, design, and execution of welded joints involving load-bearing reinforcing steel bars. It applies to both workshop and site welding conditions.
