What is the EN ISO 15614-3 Standard?

The EN ISO 15614-3 standard is part of the EN ISO 15614 series, which defines welding procedure qualification tests for cast iron materials. Due to the structural characteristics of cast irons and their susceptibility to cracking during welding, specific assessment criteria are applied to these materials.

The standard covers;

• Verification of the welding procedure specification (WPS),

• Assessment of cast iron material groups,

• Preheating and post-weld heat treatment requirements,

• Control of welding parameters,

• Non-destructive testing methods,

• Mechanical tests and macro-examinations

are included.

How is the EN ISO 15614-3 Welding Test Procedure Performed?

The welding procedure test is performed on test specimens that represent actual production conditions.

The process generally consists of the following stages:

• Preparation of the preliminary welding procedure specification (WPS),

• Preparation of the cast iron test specimen,

• Execution of the welding process using the specified parameters,

• Visual testing (VT),

• Non-destructive testing (PT, MT, RT, or UT),

• Performance of mechanical tests,

• Macro-section examinations,

• Evaluation of results,

• Preparation of the WPQR document

Why is EN ISO 15614-3 Applied?

The EN ISO 15614-3 standard is applied to verify the reliability and repeatability of welding operations performed on cast iron materials.

The primary reasons for its application are as follows:

• Technical validation of welding procedures,

• Reduction of the risk of cracks and defects,

• Enhancement of production safety,

• Standardization of weld quality,

• Ensuring traceability,

• Compliance with international standards.
