Welders must pass specific performance qualification tests outlined in the standard. These tests simulate the actual positions and joint types used on the construction project. 3. Welding Procedure Specifications (WPS)
EN ISO 17660-1 is the international quality standard for welding load-bearing reinforcing steel joints. It ensures safety, structural integrity, and compliance in reinforced concrete structures worldwide.
Accessing the official (or the BS EN version in the UK) is essential for: en iso 176601 pdf
SIST EN ISO 17660-1:2007 - Welding Load-Bearing Reinforcing Steel
The standard mandates that welding operations must be overseen by qualified . The level of technical knowledge required (Comprehensive, Specific, or Basic) depends on the diameter of the bars being welded and the complexity of the tasks. Welder Performance Qualification (WPQ) Welding Procedure Specifications (WPS) EN ISO 17660-1 is
The standard outlines that the welding coordinator must verify the material certificates before production begins. This prevents hydrogen cracking and brittle failures in the heat-affected zone (HAZ). Quality Requirements and Personnel Qualification
Weldable reinforcing steels with specified characteristic yield strengths. Welder and Welding Operator Qualification
Ensuring the tensile strength of the welded joint meets or exceeds the specified characteristic yield strength of the parent reinforcing bar. 3. Welder and Welding Operator Qualification
