Not all rebar is weldable. The standard mandates that the base metal (the rebar) must possess suitable weldability.

Introduction In the fields of civil engineering and construction, the integrity of concrete structures relies heavily on the quality of the steel reinforcement inside them. EN ISO 17660-1 is the international standard that governs the welding of reinforcing steel. Professionals searching for an "EN ISO 17660-1 PDF" are typically looking for the specific guidelines required to ensure structural safety, welder qualification, and compliance with building regulations.
What is EN ISO 17660-1? EN ISO 17660-1, titled "Welding — Welding of reinforcing steel — Part 1: Load-bearing welded joints," is a standard developed by the International Organization for Standardization (ISO) and adopted by the European Committee for Standardization (CEN).
It specifies the requirements for the welding of reinforcing steel used in concrete structures. The standard covers various aspects of the welding process, including:
Scope and Application This standard is critical for "load-bearing" joints, meaning any weld that is responsible for transferring stress within a structure. It applies to:
It is used by structural engineers, welding coordinators, and contractors to ensure that the steel framework of a building or bridge can withstand the loads it will face during its service life.
Key Requirements Found in the Document When reading the PDF of this standard, users will find strict criteria regarding:
The Transition: EN ISO 17660 vs. EN ISO 18255 It is important for technical professionals to note the recent evolution of this standard. In 2023 and 2024, the welding of reinforcing steel standards underwent a transition.

Conclusion EN ISO 17660-1 remains a foundational reference for the welding of reinforcing steel. It ensures that the skeleton of our infrastructure—concrete reinforcement—is fused together with safety and precision. For any professional in the construction industry, obtaining the official, current version of this document (or its successor, EN ISO 18255) is a necessary step in maintaining quality assurance and regulatory compliance. en iso 176601 pdf
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. Not all rebar is weldable
"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, titled "Welding — Welding of reinforcing steel — Part 1: Load-bearing welded joints," is a critical international document for the construction and civil engineering industries. It provides the technical framework for the design, execution, and testing of welded joints intended to transmit design loads in reinforced concrete structures. Overview of EN ISO 17660-1
Developed by CEN and ISO, this standard defines requirements for welding, inspecting, and testing load-bearing joints in reinforcement. It applies to both workshop and on-site welding of weldable reinforcing steel, generally for statically loaded structures.
Key Requirements: Covers various joint types (butt, lap, strap, cross), welding processes, and qualification of personnel.
Part 1 vs. Part 2: EN ISO 17660-1 covers structural load-bearing connections, whereas Part 2 addresses non-load-bearing tack welds for positioning.
Accessing the PDF: The 2006 version is the standard, available for purchase through ISO, BSI, or ANSI.
