There are 16 different welding techniques for plastics. The choice of which one to use for any particular application depends on a number of factors, including material, wall thickness, component size and complexity, and required production rate.
Plastics are widely used in a range of different industries, including aerospace, automotive, medical, oil and gas and power, where their various properties provide benefits related to durability, weight and more.
Welding is typically the preferred method for joining thermoplastics as it creates a strong bond by fusing the parts together by introducing heat to the weld through mechanical movement, an external heat source or through electromagnetism.
This presentation will describe each of the 16 welding techniques, together with its advantages/disadvantages and examples of applications.
TWI Technology Fellow, Mike Troughton will present at the event alongside Principal Project Leader, Scott Andrews.
Who Should Attend?
The FREE online event is open to both TWI Industrial Members and non-Members, and is ideal for anyone who is using, or thinking of using, thermoplastic materials.

Get an overview of the different techniques used for welding thermoplastic materials, including an insight into their advantages and disadvantages, from our world-leading experts.
Mike has been carrying out research for the plastics industry for over 30 years, and at TWI, he is responsible for co-ordinating all R&D, consultancy and training activities in the area of plastics. Mike’s main areas of expertise include the welding, inspection and mechanical testing of polyethylene (PE) pipes, on which he has written over 30 technical papers, and he is also the editor of the Handbook of Plastics Joining – A Practical Guide. Mike has managed over 150 research and consultancy projects for clients around the world, he is Chairman of the British Standards Committee on plastics welding, and is also a member of various ISO, CEN, ASTM, IIW, AWS and ASME committees on the welding of plastics and plastics pipes.
Principal Project Leader, Polymer and Composite Services
Scott is currently working as a principal project leader in the novel polymer technologies section at TWI. Scott has been involved in plastics welding research for over 20 years. His primary role is to lead and deliver research projects relating to plastics welding, typically providing plastics welding consultancy for medical and automotive products (in particular joint design for welding), proof of welding feasibility, plastics welding troubleshooting, welding machine specification and validation for entering 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 covers all plastics welding processes - in particular ultrasonic welding, plastics welding equipment, analysis of plastic welds, plastic materials - including high-temperature thermoplastics as well as wood welding and wood polymer composite welding. 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, oil and gas, construction).
