The EN ISO 17660-1 standard, titled "Welding — Welding of reinforcing steel — Part 1: Load-bearing welded joints," is a critical international document for the construction and civil engineering industries. It provides the technical framework for the design, execution, and testing of welded joints intended to transmit design loads in reinforced concrete structures. Overview of EN ISO 17660-1
Developed by CEN and ISO, this standard defines requirements for welding, inspecting, and testing load-bearing joints in reinforcement. It applies to both workshop and on-site welding of weldable reinforcing steel, generally for statically loaded structures.
Key Requirements: Covers various joint types (butt, lap, strap, cross), welding processes, and qualification of personnel.
Part 1 vs. Part 2: EN ISO 17660-1 covers structural load-bearing connections, whereas Part 2 addresses non-load-bearing tack welds for positioning.
Accessing the PDF: The 2006 version is the standard, available for purchase through ISO, BSI, or ANSI.
For detailed technical specifications, including weld quality and specific welding methods (e.g., MAG, MMA), please refer to the full standard documentation. ISO/DIS 17660-1 - Load-bearing welded joints
The "Executioner" (the contractor or welder) is responsible for ensuring the welding process meets the standard. This requires a Welding Procedure Specification (WPS) and qualified welders.

SIST EN ISO 17660-1:2007 - Welding Load-Bearing Reinforcing Steel
EN ISO 17660-1 is the definitive international standard for load-bearing welded joints in reinforcing steel. It provides a technical framework to ensure that welded rebar can safely transmit design loads within concrete structures. Key Requirements of EN ISO 17660-1
The standard mandates strict controls to prevent degradation of the steel’s mechanical properties. Essential components include: The EN ISO 17660-1 standard, titled "Welding —
Materials & Design: It covers weldable and stainless reinforcing steels, specifying how joints like butt, lap, strap, and cross-joints should be prepared to achieve full load-bearing capacity.
Welding Procedure Specification (WPS): All welding must follow a written WPS that has been qualified through a Welding Procedure Qualification Record (WPQR).
Personnel Qualification: Welders and welding operators must be qualified according to ISO 9606-1 or ISO 14732, and work must be overseen by a designated welding coordinator.
Quality & Testing: The standard references quality levels from ISO 5817 and requires production weld tests to verify structural performance. Core Differences: Part 1 vs. Part 2
Reinforcement welding is split into two distinct standards depending on the weld's purpose:
EN ISO 17660-1 (Load-Bearing): Used when the weld is intended to transmit specified design loads.
EN ISO 17660-2 (Non-Load-Bearing): Used for "tack welds" meant only to hold rebar in place during transport or concreting. Critical Limitations The Ultimate Guide to EN ISO 17660-1: Understanding
Static Loading Only: This standard applies strictly to statically loaded structures. For fatigue-loaded structures, significant reductions in fatigue strength must be calculated.
Excluded Production: It does not cover factory-produced welded fabrics or lattice girders made with multiple spot-welding machines. Helpful Resources
