(EWF), or industry-specific qualifications such as those for underwater welding or

aerospace applications.

The Welder Qualification Testing Process

Understanding the testing process can help welders prepare effectively for certification.

While specifics vary based on certification type, some common elements apply.

Preparation and Welding Procedure Specification (WPS)

Before testing, welders often review the Welding Procedure Specification (WPS), which

outlines the parameters for the weld including type of base metals, filler metals, welding

process, preheat and post-weld heat treatment requirements, and welding position.

Adhering to the WPS during the test is critical for passing.

The Welding Test Coupon

During the qualification test, welders are asked to weld a test coupon — a metal sample

prepared in a specific size and shape. The test may require multiple weld passes and

different welding positions such as flat, horizontal, vertical, or overhead.

Visual and Mechanical Inspection

After the welding is complete, the test coupon undergoes thorough inspection. Visual

inspection checks for surface defects like cracks, porosity, or undercut. Mechanical tests

may include bend tests, tensile tests, or radiographic examinations (X-rays) to detect

internal flaws.

Retesting and Documentation

If a welder fails any part of the test, they typically have opportunities to retake specific

sections. Once qualified, the welder receives documentation or a certificate that specifies

the welding process, positions, and materials they are qualified to work with. Maintaining

these records is important for future employment and project bids.

details the welding parameters, including electrode type, current, voltage, travel speed,

and shielding gas. The WPS serves as a guideline to ensure that the welder performs the

test under standardized and reproducible conditions.

2. Performance Qualification Test

The core of welder qualification is the performance test, where the welder executes a

weld according to the WPS. This may involve welding on test coupons or plates using

designated welding techniques and positions. The test weld is then subjected to various

evaluations.

3. Inspection and Testing

Evaluation of the test weld includes both non-destructive testing (NDT) and destructive

testing:

Visual Inspection: The initial check for surface defects, weld profile, and

1.

adherence to specifications.

Radiographic or Ultrasonic Testing: NDT methods to detect internal flaws such

2.

as cracks or porosity without damaging the weld.

Destructive Testing: Techniques such as bend tests, tensile tests, or macro

3.

etching examine the mechanical properties and internal quality of the weld.

Successful completion of these tests confirms the welder’s qualification.

4. Documentation and Certification

Upon passing the required tests, the welder is issued a qualification certificate, which

details the scope of their qualification — including welding processes, positions, and

materials. This certificate is typically valid for a set duration, often six months to two

years, after which requalification may be necessary, especially if the welder has not

performed the qualified process recently.
