ISO 15610:2024

Overview

ISO 15610:2024 is an international standard developed by the International Organization for Standardization (ISO) that sets out the requirements for the specification and qualification of welding procedures for metallic materials, focusing on qualification based on tested welding consumables. This standard expands upon ISO 15607 and provides a clear framework for qualifying welding processes by utilizing published and tested welding consumable data. ISO 15610:2024 is especially relevant for industries aiming to ensure consistent weld quality, optimize qualification processes, and meet compliance requirements in metallic material fabrication.

Key Topics

• Scope and Limitations:

  • Applicable to butt welds and fillet welds in parent material groups 1.1, 8.1, 21, 22.1, and 22.2, as defined in ISO/TR 15608.
  • Limited to material thicknesses up to 40 mm for groups 1.1 and 8.1, and up to 20 mm for groups 21, 22.1, and 22.2.
  • Fillet welds must have a minimum throat thickness of 1 mm.

• Exclusions:

  • The standard does not apply when specific properties are required for the welded joint, such as hardness, impact properties, preheating, controlled heat input, interpass temperature, or post-weld heat treatment.

• Welding Processes Covered:

  • The standard includes a comprehensive list of welding processes such as manual metal arc welding, MIG/MAG welding, TIG welding, plasma arc welding, and oxyacetylene welding.

• Qualification Process:

  • Leverages tested welding consumables and manufacturer’s published data for qualification.
  • Includes requirements for producing a preliminary welding procedure specification (pWPS) and a welding procedure qualification record (WPQR).

• Restrictions:

  • Qualification is tied to the specific manufacturer, trade name, and conditions stated in the consumable’s published data.
  • Certain parameters such as welding position, gas type, and electrical settings must align with consumable specifications.

Applications

ISO 15610:2024 is applied by welding engineers, manufacturers, and quality assurance professionals in the fabrication and assembly of metallic structures, particularly where streamlined welding procedure qualification is desired. It is highly useful in sectors such as:

• Steel and aluminum fabrication, including construction, transportation, machinery, and manufacturing industries.
• Pressure vessel and piping construction, where specific material groups and weld types are involved.
• Automotive and aerospace manufacturing, requiring repeatable procedure qualifications based on established consumable performance.
• General fabrication and maintenance, where the use of pre-tested consumable data simplifies compliance and speeds up the qualification process.

By enabling welding procedures to be qualified without extensive in-house testing, organizations can achieve:

• Faster time-to-market for new products.
• Reduced qualification costs.
• Assurance of compliance with international best practices.
