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.

Elias wiped the grit from his goggles and stared at the blueprints spread across a makeshift table of plywood and sawn-off rebar. The San Marco bridge was more than just a project; it was a structural puzzle. Thousands of tons of concrete would soon depend on the integrity of the steel skeleton Elias was currently overseeing.
"We’re behind schedule," his foreman, Marek, grunted, pointing to a stack of lap joints. Marek was an old-school welder who believed a "good bead" was enough. "Just run the arc. A weld is a weld." Elias shook his head, pulling a worn, digital copy of EN ISO 17660-1 on his tablet. "Not for these joints, Marek. These are load-bearing welded joints
. Under this standard, we don't just 'run the arc.' We have to ensure every one of these can transmit the design loads of the entire bridge deck". He pointed to a section of the document titled Requirements for Materials, Design, and Execution
. "Look at this. We’re working with weldable reinforcing steel and stainless bars. If we don’t follow the specific Welding Procedure Specification (WPS)
, we risk structural failure. The standard is very clear: this part of the ISO only applies to static loaded structures —and this bridge is exactly that". "I've been welding for twenty years," Marek argued.
"And that’s why you’re the best," Elias countered calmly. "But the standard requires more than just skill. It requires qualification of welding personnel and rigorous examination and testing
. We need production weld tests, tensile checks, and shear strength logs to prove these joints won't snap under the weight of ten thousand commuters".
Elias walked Marek over to a cross-joint between a reinforcing bar and a steel connection device. "Even this connection to the insert anchors is covered by
. If it were just a tack weld for assembly, we could look at Part 2. But this? This is the anchor of the whole system".
Marek sighed, finally taking the tablet. He scrolled through the annexes, looking at the test specimen diagrams and the production log examples. He looked back at the steel grid, then back at the standard.
"Alright," Marek muttered, reaching for his helmet. "Let's do it by the book. I don't want my name on a bridge that can't hold its own weight."
Elias smiled. The San Marco bridge wouldn't just be built on concrete and steel; it would be built on the precise, unyielding rules of a PDF that kept the world from falling apart. or how this standard differs from ISO 17660-2 for non-load bearing joints? SRPS EN ISO 17660-1:2009
The EN ISO 17660-1 standard provides the essential technical framework for the welding of load-bearing reinforcing steel in concrete structures. This international standard ensures that welded joints intended to transmit specified loads—whether in workshops or on-site—meet rigorous safety and quality requirements to maintain the structural integrity of buildings and infrastructure. Scope and Applications
EN ISO 17660-1 is primarily applicable to load-bearing welded joints made from weldable reinforcing steel and stainless reinforcing steel.
Structural Focus: It applies strictly to static loaded structures; fatigue-loaded structures require additional strength reduction considerations.
Joint Coverage: It covers connections between reinforcing bars, as well as joints between bars and other steel components like insert anchors and connection devices.
Exclusions: The standard specifically excludes factory-produced welding fabric (mesh) and lattice girders made with multiple spot or projection machines. Non-load-bearing joints (tack welds) are covered under ISO 17660-2. Key Technical Requirements Short useful story: EN ISO 17660-1 (welding —
The standard establishes strict protocols for every stage of the welding process to ensure the final joint matches the strength and ductility of the parent material.
Welding Personnel and Coordination: Because rebar welding requires specialized skills, the standard specifies that both welders and welding coordinators must possess a verified level of technical knowledge, often referencing ISO 14731 and ISO 9606-1.
Process and Joint Design: Permitted welding processes include manual metal arc (111), MAG welding (135), and resistance spot welding (21). The standard provides detailed geometry and preparation requirements for several joint types: Butt joints: Designed for full load-bearing capacity. Lap and Strap joints: Used for overlapping bars. Cross joints: Evaluated based on a "shear factor" ( Sfcap S sub f ) specified in design drawings.
Quality Management: Compliance is demonstrated through a documented Welding Procedure Specification (WPS) and a Welding Procedure Qualification Record (WPQR). Production logs and mechanical testing of specimens are mandatory to verify ongoing quality. Importance in Engineering
In modern construction, welding is often preferred over traditional tie wire for creating heavy-duty reinforcement cages that must maintain their shape during transport and concrete pouring. By standardizing these practices through EN ISO 17660-1, engineers can reliably use welded splices to optimize load distribution and enable complex structural designs that might be impossible with mechanical laps alone.

Ensuring Structural Integrity: A Critical Look at EN ISO 17660-1
The safety and durability of modern concrete structures, from high-rise buildings to critical bridges, depend heavily on the strength of their internal reinforcement. EN ISO 17660-1 is the foundational international standard that ensures the quality and reliability of load-bearing welded joints in reinforcing steel. By establishing rigorous requirements for materials, design, and execution, it provides a technical framework that prevents structural failure in static-loaded environments. 1. Scope and Core Applications
EN ISO 17660-1 applies specifically to the welding of weldable reinforcing steel and stainless reinforcing steel. Its primary focus is on load-bearing joints—those intended to transmit design loads between bars or between bars and other steel components like insert anchors or connection devices.
Settings: It is applicable for both workshop fabrication and on-site construction.
Exclusions: The standard does not apply to non-load-bearing (tack) joints, which are instead covered by EN ISO 17660-2 , nor does it cover factory-produced welding fabrics using multiple spot-welding machines.
Loading Constraints: Its requirements are strictly for static loaded structures. For structures subject to fatigue loading (dynamic stress), the standard recommends significant reductions in the fatigue strength of the steel. 2.

How to Implement the Standard (Quick Checklist)
Once you purchase your EN ISO 17660-1 PDF, use this checklist to audit your current rebar welding operations:
- Verify the Rebar Grade: Does your steel mill certificate match the weldable grades listed in Clause 5?
- Check the Welding Procedure (WPS): Is your WPS qualified to ISO 15614-1? The standard prohibits "non-qualified" guesswork.
- Inspect the Welder’s Certificates: Do they hold a valid ISO 9606-1 certificate specifically for rebar?
- Measure Weld Profiles: Use a weld gauge. Are the throat thickness and leg length correct? (Table 2 of the standard provides limits).
- Post-Weld Inspection: Clause 9 requires visual inspection (VT) of every weld, plus periodic magnetic particle (MT) or ultrasonic (UT) testing for critical splices.
