Welding rebar to structural steel plates or sections. Key Technical Requirements

Limitation: You cannot print, download, or save the file. But for a quick cross-check of a preheat temperature or test requirement, this is free and legal.

The fastest way to get the official read-only PDF is through the national standards organization in your country.

When working with an official EN ISO 17660-1 PDF document, users will find that the core text is divided into several strict quality assurance pillars. 1. Material Weldability

The standard is explicitly split into two documents:

A formal WPS must be created for each welding process.

The standard does not cover every type of welding. It explicitly excludes factory production of welding fabric (e.g., standard reinforcement meshes) and lattice girders that are manufactured using multiple spot welding machines or multiple projection welding machines. Additionally, the requirements of this standard are . It does not cover applications where the welds would be subject to significant dynamic or impact loading (such as in seismic zones) unless specifically considered.

Welding must be performed by qualified welders. According to , welders must hold valid welder qualification certificates tailored to the welding process and materials used (often in accordance with ISO 9606-1 ). 4. Quality Control and Inspection

. It applies to work performed both in specialized workshops and directly on-site. Load-Bearing vs. Non-Load-Bearing The standard is divided into two distinct parts: Part 1 (EN ISO 17660-1):

Offers practical guidance on test specimens, report templates, and evaluation criteria. 7. How to Access the Standard PDF

If you want, I can draft the full PDF text (3–10 pages) following that structure and include sample test templates and label examples — tell me target length and any audience focus (manufacturer, QA, regulator).

The standard classifies and regulates specific joint geometries designed to handle stress distributions. Butt Joints (Direct Splices)
