Witness & Prepare Welder Qualification

Welder Qualification is a critical process that certifies a welder’s ability to produce welds that meet specific standards and project requirements. At MB Engineering & Inspection Services, we offer comprehensive welder qualification services, including both preparation and third-party witnessing, to ensure the highest standards of skill verification, quality assurance, and regulatory compliance.

What is Welder Qualification?

Welder qualification is a formal assessment in which a welder demonstrates proficiency in a specified welding process, position, and material group, as mandated by international codes such as ASME, AWS, API, and ISO. Successful qualification ensures that welders are competent to perform work on critical structures, pressure vessels, pipelines, and other high-integrity applications.

Our Welder Qualification Process

1. Review of Project & Code Requirements

We start by thoroughly understanding your project specifications, applicable standards, and client requirements. This enables us to design a qualification test that aligns with your operational and compliance objectives.

2. Pre-Test Preparation

Our experts guide welders through the qualification process, providing clear instructions on test joint configuration, welding parameters, and acceptance criteria. We help prepare all necessary documentation, consumables, and test materials to ensure a smooth assessment.

3. Test Witnessing by Certified Inspectors

All qualification tests are witnessed by our certified welding inspectors (CSWIP, AWS-CWI, or equivalent). We monitor every stage of the test weld—including joint setup, welding technique, and adherence to the Welding Procedure Specification (WPS)—to ensure strict compliance with relevant codes.

4. Inspection and Testing

Upon completion of the test weld, we coordinate or conduct required inspections:

  • Visual Examination for weld profile, surface defects, and general workmanship.

  • Non-Destructive Testing (NDT) (e.g., radiography, ultrasonic, magnetic particle) for internal integrity.

  • Mechanical Testing (e.g., bend, tensile, impact) as specified by the code or client.

5. Documentation & Certification

We prepare and submit all qualification records—including test results, inspector reports, and welder identification—to clients, contractors, or regulatory authorities. Certified welders are issued qualification certificates, valid per code and client specifications.

6. Renewal & Recertification Support

We offer ongoing support for recertification, additional qualification tests, and skills enhancement as your projects evolve or standards change.
