Welder Qualifications

TWI Certification Ltd (TWI CL), through its CSWIP certification schemes, is able to offer welder certification based on qualification testing in accordance with a wide variety of UK, US, European and International Standards. Manufacturers wishing to comply with a specific standard, regulation or client specification can have their welding operators, procedures, and brazers certified by TWI CL.

Also, as a UK Recognised Third Party Organisation (RTPO), in accordance with the UKs Pressure Equipment (Safety) Regulation 2016 (PER), PER compliant certification from TWI CL will enable welders and brazers to comply with the PER to enable them to place their pressure equipment or assemblies on the UK market.

With the UKs withdrawal from the EU, TWI CL can no longer act as an RTPO for the EU Pressure Equipment Directive (2014/68/EU) (PED). However, in order to continue offering the standard of service expected by our customers, TWI CL will be collaborating with EU RTPOs to offer compliance with the EU PED for those customers who require it (and vice versa). These partnerships will enable customers to reap the benefits of two Certification Bodies, as all assessments will continue to be conducted by your Certification Body but under the evaluation of both Certification Bodies.

More information about our RTPO and EU collaborations (including the scheme documents) can be found on our dedicated webpage

For those customers who do not require compliance with the UK PER or the EU PED, more information can be found in the scheme document here.

For NDT inspectors seeking compliance, TWI CL offers certification in accordance with the UK PER as part of its standard CSWIP NDT examinations (subject to the appropriate methods, levels and sectors selected). Compliance with the EU PED will also be available through the aforementioned partnerships, with full details on our dedicated RTPO webpage.
