What is the EN ISO 15614-6 Standard?

The EN ISO 15614-6 standard is part of the EN ISO 15614 series, which defines welding procedure qualification tests for copper and its alloys. Due to the high thermal conductivity and alloy structures of copper materials, specific parameters must be applied during welding operations.

The standard covers;

• Validation of the welding procedure specification (WPS),

• Evaluation of copper and copper alloys,

• Control of welding parameters,

• Assessments of preheating and heat input,

• Non-destructive testing methods,

• Mechanical tests and macro-examinations

are included.

How is the EN ISO 15614-6 Welding Procedure Test Performed?

The welding procedure test is performed on test pieces that represent 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 process using the specified welding 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 15614-6 Applied?

The EN ISO 15614-6 standard is used to ensure the safe and repeatable execution of welding operations on copper and copper alloys.

Key reasons for its application include:

• Technical validation of welding procedures,

• Reduction of production defects,

• Standardization of welding quality,

• Enhancement of structural safety,

• Ensuring traceability,
