The standard’s scope includes:
In modern construction, the structural integrity of reinforced concrete relies heavily on the quality of the steel connections within it. When welding is used to connect reinforcing bars (rebar), it must meet stringent safety standards to ensure the concrete structure can withstand designed loads. is the recognized international and European standard for welding load-bearing joints in reinforcing steel.
Part 1 applies to load-bearing joints that carry primary structural loads. Part 2 applies to non-load-bearing joints, such as those used for tack welds or other non-structural purposes.
Includes precise formulas for tensile strength requirements and permissible bar diameters (4 mm to 50 mm, depending on the joint type).
In modern construction, the integrity of reinforced concrete structures relies heavily on the quality of steel reinforcement joints. When welding is used to connect reinforcing bars (rebar), it is not just a matter of melting metal; it is a critical structural process that must adhere to strict engineering standards. The cornerstone standard for this application is , which focuses specifically on load-bearing welded joints . en iso 176601 pdf
: Direct end-to-end alignment with or without a backing material.
: Dedicated exclusively to load-bearing joints designed to transmit structural forces.
: Applies to weldable reinforcing steel and stainless reinforcing steel. Excluded Items : Does not cover non-load-bearing (tack) joints (see ISO 17660-2 ) or mass-produced welding fabric/lattice girders. Diameter Ranges : Covers bar diameters from 4 mm up to 50 mm
Tensile testing and bend testing of samples are required to confirm the strength and ductility of the welded joint. The standard’s scope includes: In modern construction, the
: It provides detailed guidance for four main joint configurations to ensure full load-bearing capacity: Butt joints : Welded via arc, flash, or friction processes. Lap joints : Typically using single-sided intermittent fillet welds. Strap joints

The standard mandates rigorous testing of test specimens to ensure the joints can handle the intended load capacity. Part 1 applies to load-bearing joints that carry
The document is a harmonized European Standard (EN) that has been adopted identically from an ISO standard, meaning the same technical requirements apply across all European member countries. It was officially published in September 2006 by the International Organization for Standardization (ISO).
