Summary:

• ISO 17662:2025 Scope & Updates: Replaces the older 2016 edition, providing updated requirements for calibrating, verifying, and validating production or on-site equipment where process variables cannot be economically or readily documented by subsequent inspection.
• Process Variable Control: Strictly targets equipment influencing product safety and fitness-for-purpose (such as voltage, amperage, and wire feed speed) based on the ISO 15609 series and related welding procedure specifications.
• Exclusion of Non-Applicable Stages: Clarifies that the standard applies strictly to operational production or site equipment, excluding new equipment manufacture, installation, final non-destructive testing (NDT), and post-production product testing.
• Methodical Verification (IEC 60974-14): Reinforces annual verification cycles for arc welding equipment, shifting away from basic clamp-meter checks toward dedicated primary testing instruments and static loads that accurately measure electrical and mechanical parameters.
• Documentation & Traceability: Emphasizes tighter synchronization between monitoring templates, Procedure Qualification Records (PQRs), Welding Procedure Specifications (WPS), and rapid audit evidence retrieval.

ISO 17662:2025

1. Structural Changes & Scope Expansion

• Soldering Added: The scope has been officially expanded to encompass soldering alongside brazing. 
• Stud Welding Overhaul: The sections regarding stud welding underwent an extensive technical revision to better match modern digital controls and modern micro-discharge tracking. 
• Broad Process Coverage: The standard maintains its framework for a massive multi-process ecosystem, detailing calibration protocols for:
  • Arc, plasma, resistance, gas, friction, laser beam, electron beam, and stud welding.
  • Brazing, soldering, flame cutting, surface cleaning, and pre/post-weld heat treatment (PWHT). 

2. Operational Inclusions & Strict Exclusions

• Applies to: Production operations, active workshops, and on-site facilities. It targets any variable that directly impacts product safety or fitness-for-purpose (e.g., arc voltage, current, wire feed speed, gas flow rate, and preheat temperature). 
• Strictly Excludes:
  • The initial manufacturing or mechanical installation phase of new equipment.
  • Non-destructive testing (NDT), final dimensions measuring, or quality checks on the finished product. 

3. Core Framework & Guidance Annexes

• The WPS Base: The standard relies directly on the process parameters explicitly outlined in the ISO 15609 series (Welding Procedure Specifications). If a variable is mandated in your WPS, it falls under the jurisdiction of ISO 17662. 
• Annex B (Acceptance Testing): Provides specific instructions for when welding equipment undergoes acceptance testing, ensuring that a tool's baseline capability is properly verified before moving into production. 
• Annex C (Third-Party Providers): Clarifies compliance guidelines, roles, and structural expectations when a facility contracts external calibration labs or ISO/IEC 17025 accredited calibration services.

ISO 15609 Series

• Part 1: Arc welding (ISO 15609-1) — Specifies WPS requirements for arc welding processes (such as MMA/111, submerged arc/12, gas-shielded metal arc/13, non-consumable electrode/14, and plasma arc/15). 
• Part 2: Gas welding (ISO 15609-2) — Specifies WPS requirements for gas welding metallic materials. 
• Part 3: Electron beam welding (ISO 15609-3) — Specifies requirements for electron beam welding procedure specifications. 
• Part 4: Laser beam welding and cladding (ISO 15609-4) — Specifies WPS content for laser beam welding and overlay/cladding processes. 
• Part 5: Resistance welding (ISO 15609-5) — Covers resistance spot, seam, projection, flash, and upset welding. 
• Part 6: Laser-arc hybrid welding (ISO 15609-6) — Covers combined laser-arc hybrid welding procedures. 

ISO 15609 Guide

IEC 60974-14 (Arc welding equipment — Part 14: Calibration, validation and consistency testing) specifies the requirements for the verification, calibration, and validation of arc welding power sources and external monitoring equipment. 

Core Purpose and Scope

• Verification & Calibration: Ensures that welding parameters (such as voltage, amperage, and wire feed speed) match the manufacturer's specifications or other applicable quality standards using resistive loads.
• Application Timeline: Applied at the time of initial installation and at regular user-defined intervals, or following repairs, performance drops, or use in harsh environments. 
• Exclusions: Does not apply to plasma systems used for cutting and gouging, arc striking/stabilizing devices, or low-voltage arc welding equipment designed under IEC 60974-6. 

Testing Grades and Intervals

• Standard Grade: Typically tested every 12 months to maintain baseline compliance. 
• Precision Grade: Typically tested every 6 months, or more frequently for demanding industrial applications or harsh operating conditions. 
• Process Coverage: Applies to MIG/GMAW, TIG/GTAW, MMA/SMAW, and SAW systems. Devices like the WeldScanner Checkmaster are frequently used to execute these measurements and generate traceable pass/fail reports. 

Quality Compliance

• Helps manufacturers and fabrication shops satisfy quality frameworks such as ISO 9000 and EN 1090 CE certification requirements.
