: Qualification requirements for welders and welding coordinators.
While Part 1 focuses on load-bearing joints (joints that bear structural stress), ISO 17660-2 covers non-load-bearing joints.
The EN ISO 17660-1 standard is the definitive international guideline for the welding of reinforcing steel. Specifically, Part 1 focuses on load-bearing welded joints, ensuring that structural connections in reinforced concrete meet rigorous safety and performance criteria. For engineers, contractors, and quality assurance professionals, understanding the technical nuances of this document is essential for maintaining structural integrity. Scope and Application en iso 17660-1 pdf
I am – just guidance on where to buy a legitimate PDF at a reasonable price, or if anyone knows of a freely available extract (e.g., from a technical paper or public standard preview).
The standard recognizes several welding processes suitable for reinforcing steel, including: Manual Metal Arc (MMA) welding (Process 111) Metal Active Gas (MAG) welding (Process 135) Flux-Cored Arc Welding (FCAW) (Process 136) Flash welding (Process 24) 3. Personnel Qualifications Specifically, Part 1 focuses on load-bearing welded joints,
It applies to both factory workshops and on-site welding of weldable reinforcing steel and stainless reinforcing steel. Scope and Key Requirements
: Procedures for examination, testing, and inspection. outlining requirements for materials
: 100% of welds must undergo visual inspection for surface defects, undercut, and throat thickness.
is a standard developed by Technical Committee CEN/TC 121 ("Welding") in collaboration with ISO/TC 44, outlining requirements for materials, design, production, and testing of load-bearing welded joints in reinforcing steel. Key Focus Areas:
For thicker bars or cold climates, the standard mandates preheating. The PDF includes tables showing minimum preheating temperatures based on carbon equivalent (CEV) and bar diameter.
