Coded Welding Testing – BS 4872


The Engineering College are now fully accredited as an approved TWI (The Welding Institute) Training Centre, meaning we can carry out our own inspections of test pieces. Our tutors are TWI certified to carry out training and examination of the test pieces.

Coded Welding Testing – BS 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


ASME IX/ BSEN ISO 9606 Weld Test


1 Day (Test only)

If additional training is required to get to BS 4872 standard, additional training days will be required.


Each candidate is required to attend an assessment day prior to testing to ensure the candidate is at the required level. Cost for the assessment day is £175.00 + VAT – half of this amount will be deducted from the total price of testing.

Price per BS 4872 Test £250.00 + VAT

*Additional material costs may be applied dependent on training/test taking place.

 Our welding instructors can also test to a variety of other standards, please enquire for further information
