EN ISO 15614-4 is an international standard established to verify the suitability of welding procedures applied to aluminum casting materials. This standard covers the validation of welding operations performed on aluminum castings through specific tests and inspections.
The conformity assessment process under EN ISO 15614-4 is based on validating the welding procedure using test specimens that represent actual production conditions and creating a Welding Procedure Qualification Record (WPQR).
The EN ISO 15614-4 standard is part of the EN ISO 15614 series, which defines welding procedure qualification tests for aluminum castings. Due to characteristics such as porosity, alloy structure, and heat sensitivity inherent to aluminum casting materials, specific evaluation criteria are applied to them.
The standard covers the following:
Verification of the welding procedure specification (WPS),
Evaluation of aluminum casting material groups,
Control of welding parameters,
Examination of heat input and welding sequence,
Non-destructive testing methods,
Mechanical tests and macro-examinations
The welding procedure test is performed on test specimens that represent production conditions.
The process generally consists of the following stages:
Preparation of the preliminary welding procedure specification (WPS),
Preparation of the aluminum casting 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,
Creation of the WPQR document
The EN ISO 15614-4 standard is applied to verify the reliability of welding procedures used for aluminum casting materials.
Key reasons for its application include:
Technical verification of welding procedures,
Reduction of defects that may occur during production,
Standardization of welding quality,
Enhancement of structural safety,
Ensuring traceability,
Compliance with international standards.
The EN ISO 15614-4 standard is applied in many sectors that utilize aluminum castings.
Key application areas include:
Automotive industry,
Aerospace industry,
Shipbuilding and maritime sector,
Machinery manufacturing,
Power generation systems,
Industrial equipment manufacturing,
Maintenance and repair of castings.
The equipment and techniques used within the scope of EN ISO 15614-4 are as follows:
TIG (GTAW) and MIG (GMAW) welding machines,
Shielding gas systems,
Non-destructive testing equipment (PT, RT, UT),
Mechanical testing devices,
Hardness testing devices,
Metallographic examination equipment,
Welding parameter recording systems.
This equipment is used to verify the welding procedure's compliance with standard requirements.
Verifies the reliability of the welding procedure.
Ensures consistent quality in aluminum casting welds.
Contributes to the reduction of production defects.
Supports compliance with international standards.
Strengthens traceable production processes.
Helps verify structural strength.
Testing processes may require additional time.
Welding of aluminum castings requires high technical precision.
Costs associated with sample preparation and testing may arise.
It requires a comprehensive documentation process.
It may necessitate the use of expert personnel during implementation.
Conformity assessment and certification activities carried out under the EN ISO 15614-4 Welding Procedure Test for Aluminium Castings are conducted to verify that the welding procedures applied to aluminium casting materials comply with international standards.
The inspection and certification activities performed by our organization encompass the assessment of the technical competence of welding procedures within the framework of EN ISO standards.
