Welding engineers and our other process specialists at TWI support Industrial Members in developing and qualifying welding / production procedures. This includes preparing welding procedures specifications (WPS) or reviewing existing ones according to the major welding standards, such as ASME IX, EN ISO 15609-1, AWS D1.1, and Civil Aviation Authority (CAA) procedures.
Our expertise covers all aspects of the fabrication and service life of welded components and a wide range of applications, among which are structural welding, overlay welding, hard facing and weld repairs.
This can be supported by third-party witnessing of welding procedure qualification and welder qualification (welding performance qualification); carried out by TWI Certification Ltd, a separate company created in 1993 to separate TWI's activities in the field of certification. TWI Certification Ltd is a recognised third party for the Pressure Equipment Directive (PED).
Key outputs at this phase will include:
- Process/procedure qualification
- Personnel - welder/operator - qualification
- Inputs into design reviews and quality plans
