What is the EN ISO 15614-2 Standard?

EN ISO 15614-2 is the standard governing the testing and qualification of welding procedures used specifically for aluminum and its alloys. Due to the unique characteristics of aluminum—such as its thermal conductivity and oxide layer—a distinct procedure standard has been defined for these materials.

Its scope includes:

• Welding procedure specification (WPS) qualification
• Preparation of the welding procedure qualification record (WPQR)
• Aluminum alloy group compatibility
• Welding parameter control
• Mechanical testing
• Non-destructive testing (NDT)
• Heat input and deformation control

are included.

How is the EN ISO 15614-2 welding test performed?

Aluminum welding procedure testing is performed on test specimens that replicate actual production conditions.

The process generally consists of the following stages:

• Preparation of the WPS document
• Preparation of the aluminum alloy test specimen
• Execution of the welding process (TIG / MIG, etc.)
• Visual inspection (VT)
• Non-destructive testing (UT, RT, PT)
• Mechanical tests (tensile, bend)
• Hardness and structural evaluations
• Macro-examination analyses
• Evaluation of results and generation of the WPQR

Why is EN ISO 15614-2 Applied?

This standard is applied to ensure that welded aluminum fabrications are carried out in a safe and controlled manner.

Reasons for implementation:

• Validation of welding procedures
• Reduction of aluminum welding defects
• Ensuring structural integrity
• Standardization of production processes
• Ensuring traceability
• Meeting international compliance requirements

What are the application areas?

The EN ISO 15614-2 standard is applied in many sectors utilizing aluminum and its alloys:

• Aerospace industry
• Railway vehicle manufacturing
• Automotive and light vehicle production
• Shipbuilding and marine industry
• Energy and electrical systems
• Industrial load-bearing structures
• Aluminum construction systems
