While Part 1 focuses on critical structural connections, Part 2 covers reinforcing steel welding applications that do not bear the primary structural load. These are detailed in a separate 29-page document. The two parts are often used together to cover all welding activities on a project.

This part applies to welds designed to carry structural loads (forces).

It specifies requirements for materials, design, execution, and testing of welded connections that are explicitly designed to transmit structural forces. The standard applies to both workshop and on-site welding operations. Part 1 vs. Part 2

I am – just guidance on where to buy a legitimate PDF at a reasonable price, or if anyone knows of a freely available extract (e.g., from a technical paper or public standard preview).

Refers to non-load-bearing joints (e.g., for positioning).

All welders operating on-site or in prefabrication yards must be formally qualified. Their qualification tests must align with ISO 9606-1 (or ISO 14732 for automated welding operators), using test pieces that duplicate the specific rebar diameters and joint geometries used in the actual project [1.19].

A standard is only as good as the people implementing it. This section details the necessary qualifications for welding personnel, making direct reference to documents like ISO 14732:2013 (qualification of welding operators) and outlining the tasks and responsibilities of welding coordinators ( ISO 14731:2019 ). The informative Annex B also covers the technical knowledge required of a welding coordinator for this specific application.

It applies to both factory-produced and site-welded steel bars (typically grade 400 or higher) used in concrete reinforcement.

The EN ISO 17660-1 PDF document defines rules for welding weldable reinforcing steel and stainless reinforcing steel. It covers bars, coils, and welded fabric with diameters up to 50 mm. Types of Welded Joints Covered
