This December 2025 short course will focus on the basics of welding geomembranes and understanding how to achieve a suitable weld quality, using thermal fusion welding technologies. e.g., hot wedge and hot air, and hand extrusion welders. In particular, the course will focus on: (1) welding different geomembrane polymers, (2) types of welding and equipment selection, (3) welding parameters, and (4) importance of seam testing. The following people should consider attending: engineers, regulators, CQA personnel, installers, fabricators, and end users.
Part 2: Types of Welding and Equipment Selection will focus on the following:
• Hot wedge fusion welder – solid and split wedges
• Hot air fusion welder
• Hand extrusion welder
• Adhesive and solvent welding
• Data logging technology and its benefits
• Equipment setup
