Short useful story: EN ISO 17660-1 (welding — arc welding of steels — Part 1: Terms and definitions)
Steel fabricator Marta inherited a small welding shop where projects kept failing inspection because inspectors and clients used different words for the same things. Frustrated, she tracked down EN ISO 17660-1 — the standard that defines terms for arc welding of steels used in structural work.
She read how the standard clarifies terms like “weldability,” “preheating,” “interpass temperature,” “groove weld,” and “heat-affected zone.” Marta used those definitions to rewrite her job sheets, weld procedure specifications (WPS), and client contracts so everyone spoke the same language. On the next bridge component batch, the NDT report matched the WPS exactly, rework dropped, and quotes became more accurate because estimators used the same definitions for tolerances and weld classes.
Her shop began training new hires with a one-page glossary derived from the standard. That glossary helped trainees quickly understand inspection reports and reduced errors when recording interpass temperatures and weld sizes. Clients appreciated the consistency and awarded larger contracts. Marta credited the clearer communication from adopting EN ISO 17660-1 terminology for turning her business around.
If you want, I can:
- Summarize key terms from EN ISO 17660-1 useful for welders and fabricators.
- Create a one-page glossary or checklist you can print for shop use.
- Suggest how to map the standard’s terms into your WPS or inspection reports.

Welding of Reinforcing Steel — Part 1: Load-Bearing Welded Joints
Document Status: Current International Standard (superseding EN ISO 17660-1:2006 and corresponding national standards like DIN 488, BS 4449 references).
Applicability: Europe and International markets requiring high-integrity reinforcement welding. en iso 176601 pdf
3. Welding Processes Permitted
The standard permits specific fusion welding processes for load-bearing joints. The choice of process depends on the joint geometry and site conditions.
| Process Code | Name | Typical Application | Pros/Cons |
| :--- | :--- | :--- | :--- |
| 111 | Manual Metal Arc (MMA) / SMAW | Splices, lap joints. | Versatile, good for site repairs. Slower. |
| 114 | Self-Shielded Flux Cored Arc | Splices, lap joints. | High deposition, no external gas required. Ideal for site work. |
| 135 / 136 | MIG/MAG (Gas Shielded) | Splices, prefabrication. | High quality, high speed. Requires wind shielding on-site. |
| 25 | Resistance Butt Welding | End-to-end splices. | Requires specialized equipment; usually done in prefabrication shops. |
Note: Gas Welding (Oxy-fuel) is generally NOT permitted for load-bearing structural reinforcement due to heat-affected zone (HAZ) softening.

2. Obsolete Content: Many free PDFs are scanned copies of the original 2006 draft, missing Amendment A1:2010. Amendment A1 introduced critical changes to fatigue testing requirements for dynamically loaded reinforcement (e.g., bridge decks, railway sleepers). Using an old PDF means your welds may fail fatigue verification.
3. Malware and Viruses: Cybersecurity firms report that over 30% of "free standards PDF" sites carry malware. Downloading a file named "iso176601.pdf" from an untrusted source could install ransomware or keyloggers on your network.
4. Missing Redline Versions: Only official distributors provide redline versions showing changes between the standard and its amendments. Without this, you might overlook a modified parameter.
1. Introduction and Scope
EN ISO 17660-1 is the governing standard for the welding of load-bearing reinforcing steel bars (rebar). It specifies the requirements for the welding processes, the execution, and the quality of the welds used in the fabrication of reinforcement for concrete structures. Summarize key terms from EN ISO 17660-1 useful
Key Distinction:
- Part 1 (This Guide): Covers Load-bearing welded joints. These are structural connections where the weld transfers forces between bars.
- Part 2: Covers Non-load-bearing welded joints (e.g., tack welding for assembly stability).
This standard is critical for structural engineers, welding coordinators, and site supervisors because a failure in a load-bearing rebar weld can lead to catastrophic structural collapse.
Details of the Standard
- Title: The title of the standard is "Welding - Recommendations for welding of cast iron".
- Part 1: This part specifically deals with "Preheating".
Content Overview
The standard provides guidelines on the welding of cast irons. Cast irons are a group of ferrous materials that contain a high amount of carbon (typically more than 2%) and possibly other alloying elements. Due to their composition, welding cast iron presents specific challenges, such as the formation of hard, brittle phases and the potential for cracking.
The standard likely covers aspects such as:
- Preheating Procedures: This involves recommendations on how to preheat the cast iron parts before welding to minimize thermal stresses and reduce the risk of cracking.
- Welding Processes: It may cover suitable welding processes for cast irons, such as shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), and others.
- Filler Materials: Recommendations on the selection of appropriate filler metals to match the composition and mechanical properties of the base metal are also likely included.
- Post-Welding Heat Treatment: This might involve guidance on post-weld heat treatment to relieve stresses and improve the microstructure.
