The EN ISO 17660-1 standard provides specific requirements for the welding of reinforcing steel in structural applications. It focuses on load-bearing joints, ensuring that welded connections can reliably transfer stresses in reinforced concrete structures. Key Features of EN ISO 17660-1

The Cost of Ignoring It

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.

Industries Affected by EN ISO 17660-1:2021

This standard covers the welding of:

Personnel Qualification: Welders and welding operators must be specifically certified for rebar welding. This requires passing practical tests that simulate the unique geometry and material properties of reinforcing steel.

What is EN ISO 17660-1:2021?

Welding Personnel: Qualification requirements for welders and welding coordinators.

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
