is a European and International standard that specifies requirements for materials, design, execution, and inspection of welded joints in reinforcing steel.

The standard is designed to ensure consistent weld quality and structural safety. Key sections include: 1. Welding Procedures and Approval

This article explains what this standard covers, why it matters, and how to use it. What is EN ISO 17660-1? en iso 17660-1 pdf

(often called tack welds), which are used primarily to keep components in place during transport or concreting but do not contribute to the structure's final strength. Key Technical Requirements

The standard ensures that when you weld two pieces of rebar together, the joint can carry the full weight of the structure. There are two parts to this standard: is a European and International standard that specifies

Not all steel bars are safely weldable. The standard dictates that the reinforcing steel must have a chemical composition (specifically a Carbon Equivalent Value, or CEV) that prevents cracking during the rapid heating and cooling of the welding process. 2. Welding Processes

Not all reinforcing steel can be welded easily. The standard requires verification of the chemical composition—specifically the Carbon Equivalent Value (CEV)—of the reinforcing steel to minimize the risk of cold cracking and brittle failure in the heat-affected zone (HAZ). 2.

The standard dictates strict inspection regimes, including visual inspection of all welds and non-destructive testing (NDT) to ensure the absence of cracks, excessive porosity, or lack of fusion. EN ISO 17660-1 vs. EN ISO 17660-2 It is crucial not to confuse Part 1 with Part 2:
