What is the EN ISO 15614-5 Standard?

The EN ISO 15614-5 standard is part of the EN ISO 15614 series, which defines welding procedure qualification tests for titanium and zirconium materials. Since these materials possess high corrosion resistance and specific mechanical properties, it is crucial to protect them from atmospheric effects during welding operations and to employ controlled processes.

The standard covers the following:

• Verification of the welding procedure specification (WPS),

• Evaluation of titanium and zirconium alloys,

• Control of welding parameters,

• Examination of shielding gas applications,

• Non-destructive testing methods,

• Mechanical tests and macro-examinations

How is the EN ISO 15614-5 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 test specimen,

• Execution of the welding process using the specified parameters,

• Visual testing (VT),

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

• Performance of mechanical tests,

• Macro-section examinations,

• Evaluation of results,

• Preparation of the WPQR document

Why is EN ISO 15614-5 Applied?

The EN ISO 15614-5 standard is applied to ensure the establishment of safe and repeatable production processes in the welded fabrication of titanium and zirconium.

Key reasons for its application include:

• Technical validation of welding procedures,

• Reduction of welding defects,

• Enhancement of structural safety,

• Standardization of production quality,

• Ensuring traceability,

• Compliance with international standards.
