What is the EN ISO 15613 Standard?

The EN ISO 15613 standard governs the validation of preliminary welding procedure specifications (pWPS) used in welded fabrication through pre-production testing.

This includes:

• Preparation of the preliminary welding procedure specification (pWPS)

• Test specimens prepared under production conditions

• Validation of welding parameters

• Mechanical and NDT tests

• Process repeatability

• Technical conformity assessment

are included.

The standard covers various methods such as arc welding, gas welding, resistance welding, laser/beam welding, and stud welding.

How is the EN ISO 15613 Pre-production Welding Test Performed?

Pre-production welding tests are conducted using test welds performed under conditions that most closely approximate actual production scenarios.

The process generally proceeds as follows:

• Preparation of the preliminary welding procedure specification (pWPS)

• Preparation of test coupons in accordance with production conditions

• Execution of the welding operation

• Visual inspection (VT)

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

• Mechanical testing (tensile, bend, impact)

• Technical evaluation of results

• Approval of the procedure (generation of the WPQR)

Why is EN ISO 15613 applied?

The EN ISO 15613 standard is applied to ensure the verification of welded fabrication prior to the start of production.

Reasons for implementation:

• Pre-production verification of the welding procedure

• Reduction of the risk of defective production

• Standardization of welding quality

• Enhancement of production safety

• Ensuring traceability

• Meeting international compliance requirements

What are the application areas?

The EN ISO 15613 conformity assessment process is applied in many industries:

• Pressure equipment manufacturing

• Steel structures

• Pipelines and process systems

• Shipbuilding industry

• Power generation plants

• Machinery and heavy industry manufacturing

• Welded metal manufacturing systems

Equipment and Techniques

The equipment and techniques used within the scope of EN ISO 15613 are as follows:

• Welding machines (MIG/MAG, TIG, MMA, etc.)

• Welding parameter recording systems

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

• Mechanical testing equipment (tensile, impact, bend)

• Metallographic examination equipment

• Measurement and quality control instruments

• Process monitoring and documentation systems

Advantages

• Identifies risks before production begins

• Validates the welding procedure under actual conditions

• Minimizes production errors

• Ensures quality standardization

• Establishes a traceable production process

• Facilitates international acceptance

Disadvantages

• Requires additional pre-production testing time

• May incur sample production costs

• Requires extensive testing and documentation

• Can prolong process planning

• Requires technical expertise
