Plastic Welding Training Courses

Plastic Pipe Welding Course

Designed for those with little or no previous experience of these welding processes, this course is suitable for maintenance staff, welding engineers and others who wish to install, repair and inspect plastic pipe systems for a range of applications (landfill gas, utilities, fish farming chemical storage, oil etc.).

You will be introduced to common thermoplastics (PVC, PP, PE, PVDF); key processing techniques; joint preparation; defects and how to avoid them; process control; inspection and testing; health and safety; site working; relevant standards and guidelines and practical butt fusion, socket fusion and electrofusion welding in polypropylene or polyethylene.

Successful completion of the course will give you an understanding of practical plastic welding using butt fusion, socket fusion and electrofusion as well as knowledge on how to identify different plastic materials. Trainees will learn about weld properties for plastics, how to implement procedure control and safe operation, as well as how to identify and avoid faults and defects.

An examination leading to CSWIP certification (in accordance with BS EN 13067 – Qualification Testing of Plastics Welders) can be provided following this course if required.

UK-based training will be conducted using equipment from a range of suppliers at our training centres in Middlesbrough, Cambridge or at customer premises. 

To discuss your requirements and to book a course in the UK, please fill in the online application form and we will be in touch with you within 48 hours.



Scott is currently working as a Principal Project Leader and Programme Manager for Plastics Welding Training in the Novel Polymer Technologies Section at TWI Ltd. Scott has been involved in plastics welding research for over 20 years. Scott’s primary role is to lead and deliver research projects relating to plastics welding, typically providing plastics welding consultancy for medical and healthcare devices and automotive and aerospace products, in particular joint design for welding. Scott also undertakes proof of welding feasibility programmes, plastics welding troubleshooting, welding machine specifying and validation of plastic welded products before they enter production.

In addition, Scott manages the day-to-day running of TWI’s Plastics Welder Training and Examinations business, and is currently a CSWIP approved Plastics Welding Examiner.

Scott’s areas of expertise is all plastics welding processes (automated and manual), plastics welding equipment, analysis of plastic welds and plastic materials - including high-temperature thermoplastics, wood welding and wood polymer composite welding. In addition, Scott is a certified Plastic Pipe Welding Inspector.

Scott has successfully led many small to large polymer welding projects, for a variety of applications, across a number of industry sectors (medical, automotive, power, aerospace, utilities, oil and gas, construction), most recently ultrasonic welding of the award winning ‘Innospire Go’ Nebuliser Inhaler. The Innospire Go is now in full-scale production.

Butt Fusion, Socket Fusion and Electrofusion Welding

Plastic welding creates a molecular bond between two compatible thermoplastics. Compared to alternative methods of mechanical joining such as screws or snap fits or chemical bonding using adhesives, welding is considered the superior technique as it provides higher strength and reduced cycle times.

Pressing, heating and cooling are the three standard stages of any weld. Correct amount of pressure is used throughout the heating and cooling stages in order to retain the parts in proper orientation and to improve melt flow across the interface. During the heating stage, intermolecular diffusion between the two faying surfaces happens. And lastly, cooling stage is necessary in order to solidify the newly-formed bond. Proper execution of the cooling stage has a great impact on the weld strength.

Ultrasonic, vibration, spin, hot plate, laser/infrared, radio frequency and implant are some of the common plastic welding methods. It is the heating method used in these processes that makes the difference between them. A welding machine's pressure and cooling processes depend on the machinery used during the welding process, which can vary from one machine to another machine.
