CSWIP Welding Inspector to CSWIP Plastic Welding Inspector

There is a huge number of new plastic pipelines currently being installed for utility services in the UK, and further afield, which is creating opportunities for those trained and qualified in their inspection. To help meet demand and realise this potential, TWI is offering a two-day transition course, with our expert staff, suitable for those who currently work as metal inspectors and wish to understand, identify and report better on the inspection of welded plastic pipes.

This course is built for inspectors that currently hold CSWIP Welding Inspector (fusion) – Level 2 Certification (3.1) or above. It provides candidates with an understanding of the thermoplastic materials used in piping systems, the welding techniques used to join them and inspection techniques and methodology.

We have two dates ready to book for this course at our Middlesbrough facility*:

Course Start Date	Course End Date
13 Apr 2026	15 Apr 2026
3 Aug 2026	5 Aug 2026

What will I Learn?

• A fundamental understanding of the techniques and procedures used for welding thermoplastic pipes
• Be able to understand factors that influence the quality of welds in plastics pipes
• Interpret plastic pipe fabrication drawing instructions and symbols to ensure that specifications are met
• Be able to deliver reports on inspection of welds and mechanical tests
• An ability to assess and report on welds to provided acceptance levels
• Be able to confirm whether incoming materials meet stipulated requirements and recognise how departures from specifications affect weld quality

Please note that the minimum experience requirement for this course is Certified Welding Inspector (fusion welding). This course leads to CSWIP certification, which acts as proof of your skills and knowledge and may be a requirement of some employers and regulators.

In addition to this course, all our other courses are available as bespoke options that can be tailored according to your needs. All training courses and examinations can be carried out at TWI’s Plastic Welding Training Centre in Middlesbrough, at TWI’s headquarters in Cambridge, or at customers’ premises worldwide.
