Before welding begins, a must be established. This document provides instructions for the welder. According to, a Welding Procedure Test is required to prove that the proposed procedure can produce joints that meet the strength requirements of the standard. 3. Personnel Qualification

(often called tack welds), which are used primarily to keep components in place during transport or concreting but do not contribute to the structure's final strength. Key Technical Requirements

Maintaining a high and consistent level of quality is paramount. The standard requires a quality system to ensure that all aspects of the process are controlled and documented. Clause 15 mandates the maintenance of a , for which a practical template is provided in Annex F, to ensure full traceability of all welding activities. en iso 17660-1 pdf

It defines joints intended to transmit design loads, distinguishing them from "tack" or non-load-bearing joints (which fall under ISO 17660-2 iTeh Standards Document Status & PDF Access

(often adopted as BS EN ISO 17660-1 or DIN EN ISO 17660-1) is the international standard titled "Welding — Welding of reinforcement steel — Part 1: Load-bearing welded joints." | Clause | Title | | :--- |

The standard specifies comprehensive rules for several aspects of the welding process: Materials & Design

: The official source for the standard (Part 1:2006).

EN ISO 17660-1 is not merely a set of theoretical guidelines; it is a practical manual for the workshop and the job site. The standard provides systematic guidance across several key technical areas. It applies to the welding of both carbon and stainless steel reinforcing bars and also covers joints between reinforcing steel bars and other steel components such as connection devices and insert anchors, which is particularly relevant for prefabricated assemblies. The standard requires a quality system to ensure

Welds must satisfy both mechanical strength and metallurgical requirements. EN ISO 17660-1 vs. ISO 17660-2 EN ISO 17660-1 EN ISO 17660-2 Type of Joint Load-Bearing (Structural) Non-load-bearing (Positioning) Purpose Transmit loads Fix position before concreting Requirement Higher testing requirements Lower testing requirements How to Acquire the EN ISO 17660-1 PDF

The standard specifies requirements for the welding of load-bearing joints in weldable and stainless reinforcing steel . It applies to both workshop and on-site welding for structures subjected to static loads . Core Technical Overview

Welders and welding coordinators must possess specific skills and job knowledge, often requiring certification under ISO 9606-1 Quality Management: The standard references ISO 3834-3

Disclaimer: Always ensure you are using the most current version of a standard, as they may be updated or replaced over time.

Imagine a welded rebar lap joint on a bridge abutment. The welder skipped preheating because “it looked fine.” The weld passes visual inspection but fails a bend test per EN ISO 17660-1. Months later, under live load, a brittle fracture occurs.
