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

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.
