Welding codings BS EN 4872

BS 4872 applies to a wide range of general fabrication work where an approved welding procedure test is not required. Welds would usually be carried out in accordance with written instructions and the test weld, subject to visual or surface inspection, a bend and fracture test. Depending on particular weld configuration, each test can cover a range of welding variables e.g. material thickness and welding positions. This welder competency test does not require formal signatures to stay current, however the standard recommends re-approval every two years and states that the re-approval of the welder shall take place if:

1. The welder is required to work outside the scope of their current approval
2. The welder changes their employer without transfer of their certificate
3. Six months or more have elapsed since the welder undertook any welding
4. There is a specific reason to question the welders ability
