Indus Industrial Group supplies professional-grade Automated Hot Wedge Geomembrane Field Welding Machines engineered for high-speed, continuous dual-track fusion welding of HDPE, LLDPE, PP, and PVC geomembranes in thicknesses from 0.5mm to 3.0mm. Operating in strict accordance with DVS 2225 and ASTM D4437 specifications, these heavy-duty field welders feature digital closed-loop PID temperature and speed control, high-torque drive motors, and dual-track pressure rollers that create a continuous test channel for non-destructive on-site compressed air pressure testing.

High-integrity sealing of hundreds of thousands of square meters of geomembrane liners on Iraqi canal lining and reservoir projects requires field welding equipment capable of maintaining continuous, flawless thermal fusion under dusty, high-temperature job-site conditions. Our Automated Hot Wedge Welders utilize a precision solid-copper or stainless steel heated wedge delivering up to 1800W–2200W of heating power with temperatures digitally adjustable up to +450°C.
The dual-track pressure roller assembly applies adjustable compressive force (up to 1,000 N) to fuse overlapping geomembrane sheets while creating an un-welded central air channel (typically 10mm wide) between two parallel 15mm weld seams. This test channel allows quality control inspectors to seal both ends with a test needle and inject compressed air to 2.0–2.5 Bar to non-destructively verify seam integrity along the entire weld length according to ASTM D5820.
Engineered with high ground-clearance stainless steel chassis and heavy-grip drive wheels, the machine navigates uneven earthen subgrades, gravel slopes, and dusty trenches without stalling. Operating on 230V single-phase generator power, Indus supplies complete turnkey packages including welding machines, test needles, manometer gauges, and spare heating wedges from our Erbil and Basra technical centers.
A test needle connected to a pressure gauge and hand pump is inserted into the central air channel between the two parallel weld tracks. The channel is pressurized to 2.0 to 2.5 Bar. If pressure holds steady for 5 minutes without dropping, the seam is 100% certified watertight per ASTM D5820.
Yes. With up to 2200W heating power and digitally controlled hot wedge temperature up to +450°C, the machine pre-heats and fully fuses thick 2.5mm HDPE liners even in winter ambient temperatures down to 0°C.
Yes. Indus stocks original spare copper wedges, thermocouple sensors, drive chains, and pressure rollers at our Erbil and Basra service centers for immediate job-site dispatch.
