DNV Welder Qualification Certificate Test

🌍 What is DNV?

DNV (Det Norske Veritas) is a globally recognized classification society and certification body based in Norway. It sets strict international standards for safety, quality, and environmental sustainability across various industries including:

• Shipbuilding & Marine
• Oil & Gas
• Offshore Platforms
• Renewable Energy
• Manufacturing & Heavy Fabrication

🎯 Purpose of the DNV Welder Qualification Test

The DNV Welder Qualification Certificate Test is conducted to ensure that a welder has the required skill and competence to perform welds safely, correctly, and reliably in accordance with DNV rules and international welding standards.

The goal is to qualify welders for:

• Shipbuilding and ship repair
• Offshore and onshore structural fabrication
• Pressure vessels and pipelines
• Subsea equipment and marine systems

🛠️ Welding Processes Covered

Welders can be tested and certified in one or more of the following welding processes:

• SMAW – Shielded Metal Arc Welding (Stick)
• GTAW – Gas Tungsten Arc Welding (TIG)
• GMAW/FCAW – MIG/MAG and Flux-Cored Welding
• SAW – Submerged Arc Welding

📐 Test Parameters

The test is conducted under supervision of an Authorized DNV Surveyor or an approved Third Party, and includes:

• Material Type: Carbon Steel, Stainless Steel, Duplex, Inconel, Aluminum, etc.
• Pipe or Plate: Depending on the application
• Positions: 1G, 2G, 3G, 4G, 5G, 6G (All Position)
• Thickness Range: As per project or industry requirement

🔬 Testing and Evaluation

✅ The welder must pass:

• Visual Inspection – for surface defects and profile
• Non-Destructive Testing (NDT):
  • RT (Radiographic Testing)
  • UT (Ultrasonic Testing)
  • LPT/MPT as required
• Mechanical Tests:
  • Bend Test
  • Tensile Test (optional)
  • Macro/Micro Examination (if applicable)

📄 Certification

After successful completion, the welder receives a DNV-endorsed Welder Qualification Certificate, which includes:

• Welder’s name and ID
• WPS number used
• Welding process
• Base and filler materials
• Thickness and diameter range qualified
• Validity period (typically 2 years with continuity)

📌 Validity & Renewal

• Validity: Usually 2 years
• Continuity Records: Must be maintained to avoid expiry
• Retesting: Required if there’s a break in welding activity or if performance is in question

✅ Benefits of DNV Welder Certification

• Globally recognized by shipyards, oil & gas, and offshore projects
• Boosts employability for overseas and high-value contracts
• Proves welder’s technical competency and skill
• Mandatory for many marine and offshore engineering projects
• Enhances worksite safety and quality control

👨‍🏭 Who Should Take This Test?

• Welders working in or aiming for jobs in:
  • Shipyards
  • Offshore rigs and platforms
  • Marine fabrication
  • Pressure vessel & pipeline industries
• Fabrication shops involved in DNV-classified projects
• Welders seeking to improve their career profile with international certification
