At Firefly Welding, we understand that the foundation of any successful fabrication project is the skill and qualification of the welders performing the work. That is why we offer comprehensive welder qualification testing services that ensure every weld performed in our facility meets the highest standards of quality, safety, and compliance.
We have had the privilege of working closely with a wide range of clients across Europe, helping to certify their welding teams through rigorous testing processes. Whether it is for large-scale industrial projects or smaller-scale bespoke works, we have earned a reputation for delivering welders who can meet the most demanding specifications.


The Importance of Welder Qualification Testing
Welder qualification testing is a critical process designed to verify a welder’s ability to perform welds that meet the required technical and regulatory standards. It is essential for ensuring that every weld is completed safely, efficiently, and with the utmost integrity. This process ensures that welders are fully equipped to manage the specific demands of a project, ensuring reliable and high-quality results every time.
Successful qualification verifies that the welder is not only capable of producing flawless welds but also adheres to the necessary procedures for compliance and safety. This certification is essential for industries where the quality of welds is paramount, such as oil and gas, pharmaceuticals, food, and beverage, and more.
Our Approach to Welder Qualification
Firefly has experience in conducting welder qualification tests for clients across a wide range of sectors, from oil and gas to pharmaceuticals, food and beverage, and everything in between. We have developed a streamlined and effective process for testing welders at our Wirral facility, ensuring that each candidate is evaluated against the highest standards.
Working in partnership with Apave (formerly Iris NDT), one of the leading names in non-destructive testing (NDT), we provide a comprehensive testing and certification process. Our team ensures the testing methods and procedures are up to date with the latest industry requirements and that the results are fully documented for traceability and compliance.
Testing Process and Standards
At Firefly, we follow internationally recognised standards for welder qualification, including those set by ASME and EN. Our qualified assessors evaluate welders based on the following criteria:
- Weld Procedure Specification (WPS): We begin by setting out the exact parameters for the welding procedure, such as the type of materials to be welded, welding position, and welding process.
- Practical Test: The welder is tasked with conducting welding work based on the WPS, using the specified materials and conditions. This hands-on test ensures that they can perform welds that meet the specified quality and safety requirements.
- Non-Destructive Testing (NDT): To ensure the integrity of the welds, the samples are subjected to NDT processes such as ultrasonic testing, X-ray inspection, or dye-penetrant testing. These methods identify any potential defects or weaknesses in the welds without damaging the test material.
- Documentation & Certification: Once testing is complete and the welds are approved, the welder receives formal certification. We maintain a detailed record of each test, including the welder’s qualifications, test results, and NDT reports, providing full traceability for each candidate.
