Welder Certification
Professional welding personnel certification and authorization
What is Welder Certification?
Welder certification is the documentation of welders' competencies after passing theoretical and practical exams according to relevant standards, and evaluating test pieces through non-destructive (NDT) and destructive tests. This certification guarantees that welders can perform quality work in accordance with specific welding procedures.
Certification Process
1) Welder candidate welds test piece according to specified standard. 2) Test piece is inspected by RT (Radiographic), UT (Ultrasonic) or other NDT methods. 3) Destructive tests such as bend and tensile are applied if required. 4) Certificate is issued to welders meeting standard acceptance criteria.
Importance of Welder Certification
- Quality Assurance: Certified welder works according to standard procedures.
- Customer and Institutional Requirements: Most projects or tenders require certified welding personnel.
- Reduced Error Risk: Trained and tested welders make fewer faulty welds.
- Traceability: Records of work done by each welder can be kept with their certificate.
- International Validity: Certificates issued according to ISO standards are recognized worldwide.
Certification Scope
- Welding Method: MAG, MIG, TIG, Electrode, SAW etc.
- Base Material Group: Steel, aluminum, stainless, nickel alloys
- Product Type: Pipe, plate, profile, casting
- Welding Position: PA (flat), PF (horizontal), PG (vertical up), PH (overhead), etc.
- Thickness and Diameter Range: Specific ranges are valid according to test piece thickness.
- Filler Metal: Solid wire, flux cored wire, electrode type
Note: Each certificate is valid for a specific combination of welding method, material group and position. Separate certificates may be required for different scopes.

Which Sectors Require Welder Certification?
There is a requirement to employ certified welders in quality and safety critical industries.
Pressure Vessel and Pipe Manufacturing
Mandatory for boiler, tank, reactor, pipeline welds
Oil and Gas Pipelines
API 1104 standard requires certified welder
Aerospace Industry
Special certification for critical structural components
Shipbuilding and Shipyards
For ship hull, tank and pipe system welds
Nuclear Power Plants
