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:

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 en iso 176601 pdf

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

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 EN ISO 17660-1 is the definitive international standard

2.1 Weldability

Not all rebar is weldable. The standard mandates that the base metal (the rebar) must possess suitable weldability.

  • Carbon Equivalent (CE): The chemical composition of the steel must be provided by the manufacturer. A common limit is $CE \leq 0.50%$ (or up to $0.55%$ with specific precautions) to avoid hydrogen-induced cracking.
  • Rebar Grades: Typically covers grades B500A, B500B, B500C, and similar high-yield steels.

1. Welding Procedure Specification (WPS)

The standard requires a WPS for all load-bearing joints. This document must detail:

  • Base material grade (e.g., B500B steel).
  • Filler material classification.
  • Welding positions (PA, PB, PC, etc.).
  • Preheating temperature (if required, based on the carbon equivalent value).

What is EN ISO 17660-1?

EN ISO 17660-1 is a European Standard (EN) that is harmonized with an international standard from the International Organization for Standardization (ISO). Specifically, this standard relates to recommendations for welding of cast iron.
