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 3 Welding Parameters will focus on the following:
• Understanding Heat, Speed, and Pressure
• Establishing Welding Windows
• Importance of Welding Windows
• Impact/Dangers/Wrinkles from Ambient conditions
• Parameter recommendations
• Pre-weld Testing
• Correct seam overlap
• What if FML is not clean (dust, water, painting)
