What is the EN ISO 15614-1 Standard?

EN ISO 15614-1 defines welding procedure qualification tests for metallic materials, specifically steels and nickel alloys. This standard outlines the necessary testing criteria to ensure that welded fabrication can be performed safely and reproducibly.

Its scope includes:

• Welding procedure specification (WPS) validation

• Creation of a welding procedure qualification record (WPQR)

• Material group suitability

• Welding parameter control

• Mechanical testing

• Non-destructive testing (NDT)

• Evaluation of heat treatment and welding sequence

How is the EN ISO 15614-1 Welding Test Performed?

The welding procedure test is carried out by preparing a test specimen under specified parameters.

The process generally consists of the following stages:

• Preparation of the WPS document

• Preparation of the steel or nickel alloy specimen

• Execution of the actual welding

• Visual testing (VT)

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

• Mechanical tests (tensile, bend, impact)

• Hardness measurements

• Macro and micro examinations

• Evaluation of results and preparation of the WPQR

Why is EN ISO 15614-1 Applied?

This standard is implemented to ensure the safety and technical suitability of methods used in welded manufacturing processes.

Reasons for implementation:

• Validation of welding procedures

• Reduction of production defects

• Enhancement of structural safety

• Ensuring traceability

• Compliance with international standards

• Supporting CE and PED processes

What are the application areas?

The EN ISO 15614-1 standard is applied in many industries:

• Pressure equipment manufacturing

• Chemical and petrochemical plants

• Power generation systems

• Steel structures

• Pipelines and process systems

• Shipbuilding industry

• Heavy industry and machinery manufacturing

Equipment and Techniques

Equipment and techniques used within the scope of EN ISO 15614-1:

• MIG/MAG, TIG, and MMA welding machines

• Automatic and semi-automatic welding systems

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

• Mechanical testing equipment (tensile, impact, bend)

• Hardness testing equipment

• Metallographic examination equipment

• Process control and recording systems

Advantages

• Technically validates welding procedures
