TWI Accreditation

Serious Engineering has been TWI accredited since 2013 to BS EN 287/9606 standards for the coded welding of carbon steel, stainless steel and aluminium.

The Welding Institute (TWI) is a third party body that certifies metal fabricators in the United Kingdom, providing independent verification of quality and capability.

BS EN 287 is the European Standard that defines the qualification testing of welders. It provides a set of universal rules to test welders’ ability to produce high quality, structurally sound, fusion welds; independent of the type of product, location or the examiner.

Why is TWI welding accreditation important?

Welding is considered a “special process” in that a single particular weld cannot be completely verified without destroying the weld. Therefore the whole welding and weld approval process that a company employs must be tested to ensure that time and time again welds are produced without defect.

Thus, accreditation provides a high level of confidence in the metal fabrication company, showing that they have the skills, resources, materials, and processes to manufacture components that will meet requirements. Accreditation is important for all industries but it’s crucial in fabrications for: oil and gas, nuclear (non-critical), PPMA, Aerospace, Construction and the fabrication of yellow goods.

How does TWI accreditation ensure quality?

When a third party such as TWI examines a fabrication company to test their qualification for a welding standard such as BS EN 287, they asses the full welding process including:

  • Procedures (W.P.S, W.P.Q.R) for reviewing technical specifications and requirements
  • Inspection and testing processes
  • Assessment of welding equipment
  • Review of shop procedures
  • Assessment of welder ability
  • Inspection of welding consumables
  • Review of storage, identification, and traceability of materials.

This examination occurs every two years to ensure that quality is maintained.

The future

Quality is at the centre of everything we do here at Serious Engineering, and accreditation is the rubber stamp that proves it.  We’ll be applying for BS EN ISO 3834 in the near future as we continue to raise the bar on quality.
