Overview
ISO/TR 23413:2019 is a technical report that provides an organized overview of ISO (and relevant IEC) standards for resistance welding. It covers the main resistance welding processes: resistance spot welding, projection welding, seam welding, flash welding, and upset (resistance butt) welding. Rather than set requirements itself, ISO/TR 23413:2019 maps the landscape of applicable standards - helping users find the right documents for quality, testing, equipment, safety and procedure specification related to resistance welding.
Key topics and requirements
This overview identifies the standards and topical areas that apply across resistance welding. Major technical topics highlighted include:
- Quality management and acceptance: reference to ISO 9000 series and ISO 14554 parts for quality requirements in resistance welding.
- Procedure specification and qualification: pointers to specification/qualification standards such as ISO 15609-5 (Welding procedure specification - resistance welding) and ISO 15614-12/13 (welding procedure tests for spot/seam/projection and upset/flash welding).
- Testing and test specimens: links to destructive testing standards (peel, tensile shear, cross-tension, fatigue) such as ISO 10447, ISO 14270, ISO 14271, ISO 14329, ISO 14324 and others.
- Measurements and instrumentation: references to the ISO 17657 series for welding current measurement (guidelines, meters, coils, calibration, verification).
- Equipment, electrodes and transformers: standards for welding equipment, electrode materials and adaptors (for example ISO 669, ISO 5182, ISO 5183, ISO 5826, ISO 8205 series).
- Weldability and procedure guidance: standards like ISO 14327, ISO 16432, ISO 16433, ISO 18595 for weldability and process-specific guidance.
- Personnel and safety: personnel qualification (ISO 14732) and occupational safety/EMC/EMF references to IEC 62135-1/2 and IEC 62822-3.
Note: ISO/TR 23413:2019 itself contains no normative references or new definitions - it functions as a road map.
Applications and who uses it
ISO/TR 23413 is a practical starting point for:
- Welding engineers and process designers selecting applicable resistance welding standards
- Quality managers and inspectors establishing acceptance criteria and test methods
- Manufacturers of welding equipment, electrodes and transformers ensuring compliance with mechanical/electrical requirements
- OEMs and automotive suppliers developing welding procedure specifications (WPS) and qualification tests
- Safety and compliance officers addressing EMC/EMF and machine safety for resistance welding equipment
