At Marine Inspection & Solutions Ltd. (MISL), we offer professional Welder Qualification Test (WQT) services designed to validate the skills and competencies of welders in accordance with national and international standards such as AWS D1.1, ASME Section IX, ISO 9606, and other client-specific codes.

🔧 What is a Welding Qualification Test (WQT)?

The Welding Qualification Test is a structured practical assessment of a welder’s ability to produce sound welds under defined conditions. It is a mandatory requirement for most fabrication, construction, marine, oil & gas, and pressure vessel industries to ensure quality and safety.

The test confirms that a welder can:

• Follow specified welding procedures (WPS)
• Produce defect-free welds
• Maintain consistency and workmanship under code requirements

✅ Why WQT is Important

• ✔️ Compliance with International Codes
• ✔️ Ensures Weld Quality and Structural Integrity
• ✔️ Reduces Risk of Failure or Rework
• ✔️ Mandatory for Project Approvals and Certifications
• ✔️ Builds Confidence of Clients & Regulatory Bodies
