Overview
EN ISO 17660-2:2006 - Welding of reinforcing steel - Part 2: Non load-bearing welded joints specifies requirements for welding weldable reinforcing steel and stainless reinforcing steel when the welded joints are non load-bearing (i.e., their strength is not accounted for in the structural design). Published by CEN/ISO, the standard applies to workshop and on‑site welding and covers materials, joint design, welding execution, personnel, quality requirements, inspection, examination and testing. Load‑bearing joints are treated separately in ISO 17660‑1.
Key topics and requirements
- Scope and definitions
- Applies only to non load‑bearing welded joints (often used as tack welds to hold bars during fabrication, transport and concreting).
- Permitted welding processes
- Includes processes referenced to ISO 4063 (examples: manual metal arc (111), shielded/self‑shielded electrodes (114, 135, 136), resistance spot (21) and projection welding (23)).
- Joint types and dimensions
- Recognises lap joints and cross joints; weld length and throat thickness are to be defined in the Welding Procedure Specification (WPS).
- Provides recommended bar diameter ranges for different welding processes.
- Materials and consumables
- Applicable to weldable reinforcing steels and stainless reinforcing steels.
- Inspection certificate normally required; carbon equivalent value (CEV), manufacturing route and delivery conditions must be determined prior to welding (with stated exceptions).
- Welding procedure control
- Requires documented WPS and, where applicable, WPQR and welding procedure tests in accordance with the referenced ISO procedure standards.
- Quality and personnel
- Manufacturers must meet quality requirements (ISO 3834‑4 elementary level) and provide welding coordination per ISO 14731 with specific knowledge for reinforcing steel welding.
- Testing, inspection and records
- Defines requirements for production weld tests, examination, destructive/non‑destructive testing of specimens, and keeping a production log.
Practical applications and who uses it
- Useful for reinforcing‑steel fabricators, precast manufacturers, site contractors, welding coordinators, QA/QC managers and structural engineers who need to ensure correct, safe tack or non load‑bearing welds in reinforced concrete works.
- Applies when specifying or verifying welding practices for rebar connections in bridges, buildings, precast elements and refurbishment projects where welds are intended only for positioning.
