Geomembrane Liners, Blind Fabrics, Tarpaulins, Truck & Rail Curtain-siders, Covers, Shade Sails, Printed Banners – in fact almost any synthetic flexible material can usually be welded. There are two types of welding technologies usually employed when welding of Industrial Fabrics.

Hot Air Overlap Welding
Hot Wedge Welding 

Hot Air Overlap Welders

Welding Industrial Fabrics with hot air is common place these days. Both Automatic Overlap welders, and Hand-held welding tools can be used to overlap weld material joins where the fabrication is ‘in-house’ – meaning the welding will be carried out on a flat, hard surface – such as a large bench top, or a hard, smooth floor.

Hot Wedge Welders

The Hot Wedge welders are an automatic machine, which has a heated ceramic wedge, that slides between the material overlap and contacts and heats both sides of the material. Grip rollers can be set up to provide correct pressure and a motor drives the machine along the length of the material. Wedge Welders are also usually designed to be used ‘on-site’ eg. welding a liner for a pond or landfill site. Welding speed, temperature, and pressure can all be controlled on board the Wedge Welding machine.
