Sellafield Limited up-skill engineers with CSWIP certification


Sellafield Limited up-skill engineers with CSWIP certification Six engineers from Sellafield Nuclear celebrated gaining a CSWIP certification in Butt Fusion and Electrofusion welding of polyethylene (PE) pipes, having successfully completed TWI’s tailored training course.



Ian Noble, a Quality Manager, from Sellafield Ltd approached TWI when a new project came up to design and install a large diameter polyethylene pipeline to carry cooling water. The successful and safe installation of the pipeline requires essential knowledge of the installation processes and procedures. As the industry’s leading experts in plastics welding, TWI were best place to deliver the training required to Sellafield’s engineers.

Andy Knight and Scott Andrews from TWI’s Polymer Section delivered the two-day training and examination course at the Sellafield Nuclear Reprocessing Site in Seascale, Cumbria. The course was designed for the specific needs of the engineers and tailored around their existing skills and experience, ensuring each candidate completed the training with a thorough knowledge of the principles and best practice of butt fusion and electrofusion welding of PE pipes.

The course involved a mixture of classroom and practical sessions and covered an introduction to common thermoplastics, welding equipment, avoidance of joint defects, health and safety, welding parameters, joint preparation, process control and inspection and testing. The training course concluded in the successful completion of a theoretical and practical examination exercise, which led to each candidate gaining a CSWIP certification in Butt Fusion and Electrofusion welding of PE pipes.
