Overview
IEC 60974-14:2018 - Arc welding equipment, Part 14 - defines requirements and practical procedures for the calibration, validation and consistency testing (collectively “verification”) of arc welding and external monitoring equipment. Applicable at installation and at user-determined intervals, this standard verifies that welding power sources, wire feeders and monitoring instruments operate to manufacturer specifications or other user-defined requirements. The January 2022 corrigendum is included in this edition.
Key Topics and Requirements
- Verification scope and exclusions: Applies to arc welding equipment and external monitoring; excludes plasma cutting/gouging systems, arc-striking/stabilizing devices and equipment designed per IEC 60974-6.
- Verification types:
- Calibration of displayed values (internal instrument readings).
- Validation of set values (operator-set parameters).
- Consistency testing to confirm repeatability of set values.
- Measurement accuracy and permitted deviations: Defines verification accuracies, tolerances and diagrammatic guidance for acceptable deviations.
- Test setup and reference instruments: Requirements for test loads, reference meters and appropriate filtering/signal conditioning when measuring welding outputs.
- Device-specific guidance: Procedures and precautions for power sources, wire feeders, pulsed/synergic controls and TIG equipment.
- Personnel and safety: Competency requirements for testing personnel and safety precautions during verification.
- Documentation and marking: Reporting format, sample verification reports and marking requirements for verified equipment.
- Informative annexes provide diagrams, measured-value formation, test methods for slope/pulse/synergic controls, TIG precautions and sample reports.
Practical Applications
- Establishing a verification program during equipment commissioning and periodic maintenance.
- Supporting quality management for welding processes by ensuring accurate instrument readings, reproducible set values and consistent welding performance.
- Guiding service shops and manufacturers in creating or benchmarking factory and field verification procedures.
- Providing test procedures for calibration labs, maintenance teams and quality engineers responsible for welding equipment performance.
Who Should Use This Standard
- Welding engineers and quality managers implementing welding process control.
- Maintenance and service personnel performing calibration and verification of welding power sources and wire feeders.
- Manufacturers developing verification procedures or documentation for equipment handover.
- Certification and calibration laboratories that test arc welding equipment.
