Introduction
Reinforcing steel bars are produced by a number of process routes and usually have a ribbed profile.
Taking these issues into account, it is apparent that both the welder and the welding coordinator
require a specific level of skill and job knowledge and that special procedures for quality assurance
need to be adopted.

Introduction
Welding — Welding of reinforcing steel — Part 2: Non load-
bearing welded joints
Reinforcing steel bars are produced by a number of process routes and usually have a ribbed profile.
Taking these issues into account, it is apparent that both the welder and the welding coordinator
require a specific level of skill and job knowledge and that special procedures for quality assurance
need to be adopted.
1 Scope
This part of ISO 17660 is applicable to the welding of weldable reinforcing steel and stainless
reinforcing steel of non load-bearing welded joints, in workshops or on site. It specifies requirements
for materials, design and execution of welded joints, welding personnel, quality requirements,
examination and testing.
Load-bearing welded joints are covered by ISO 17660-1.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 10079, EN 10080 and
ISO 16020 and the following apply.
3.1
load-bearing welded joint
welded joint used for transmission of specified loads between reinforcing steel bars, or between
reinforcing steel bars and other steel products
3.2
non load-bearing welded joint
welded joint whose strength is not taken into account in the design of the reinforced concrete structure
NOTE The purpose of a non load-bearing welded joint is usually only to keep the reinforcing components in
their correct places during fabrication, transport and concreting. The weld is often called tack weld.
