The SIGMA geomembrane welding machine is a hot-wedge welder for HDPE liner installation. With high welding power, fast welding speed and good weld quality, the machine offers stable performance, convenient operation, high welding efficiency and high reliability. It is widely used in tunnels, subways, water conservancy, aquaculture, landfill, chemical mining, sewage treatment, roofing and other waterproof anti-seepage projects, joining geomembrane sheets into a continuous, watertight seam in the field.
The SIGMA geomembrane welding machine delivers high welding power, fast welding speed and good weld quality. The machine has stable performance, convenient operation, high welding efficiency and high reliability. It is widely used in tunnels, subways, water conservancy, aquaculture, landfill, chemical mining, sewage treatment, roofing and other industries on waterproof anti-seepage projects — joining geomembrane sheet into a continuous, watertight seam.
As an HDPE liner welding machine, the hot wedge welder is the primary tool for seaming our HDPE geomembrane and pond liner in the field. The self-propelled wedge welder runs along the overlap and fuses the sheets with a dual-track weld, leaving an air-testable channel between the tracks so seam integrity can be verified on site. It pairs naturally with the rest of our geomembrane range.
In use the machine is the simplest part of the seam. The two sheets are overlapped along the seam line, the self-propelled welder is set on the overlap, and it drives itself forward while a heated wedge fuses the upper and lower membranes together. Because it is self-propelled and produces a uniform dual-track weld, hdpe geomembrane welding is fast, consistent and far less operator-dependent than hand work. The channel left between the two weld tracks is sealed at the ends and pressurised with air, so the crew can confirm seam integrity on site without cutting the weld. The result is the high welding efficiency and good weld quality the machine is built for.
A hot wedge welding machine is the workhorse of large lining jobs. It is widely used in tunnels, subways, water conservancy, aquaculture, landfill, chemical mining, sewage treatment, roofing and other waterproof anti-seepage projects, joining geomembrane sheet into a continuous, watertight barrier. The same machine works as a pond liner welding machine on aquaculture and irrigation basins and as a dam liner welding machine on water-retaining structures, so a single hdpe liner welding machine covers most of the field seaming on a project. For the membrane itself, see our HDPE geomembrane and pond liner.
Match the geomembrane welder to the liner material, thickness and project conditions. A hot-wedge welder handles long production seams quickly, while geomembrane glue and extrusion methods cover details, penetrations and repairs the wedge cannot reach. Buyers comparing a hot wedge welding machine against brands such as a Leister wedge welder should weigh weld speed, power and on-site reliability; full ratings for the SIGMA machine are issued on request. For the consumable side of installation, see our installation equipment; the welder and the glue together complete a watertight liner system.

A geomembrane welding machine — a hot wedge welder — joins geomembrane sheets into a continuous, watertight seam during liner installation. It fuses the overlapped sheets so the finished liner is sealed against seepage, and is used across landfill, water conservancy, aquaculture, sewage treatment and roofing anti-seepage projects.
The hot-wedge welder is used for HDPE geomembrane and pond liner seams, and is widely applied on dam liner, landfill and containment installations. Tell us the liner material and thickness and we will confirm the machine suits your project.
The self-propelled welder runs along the seam overlap and fuses the two sheets with a heated wedge, typically as a dual-track weld. The channel left between the two tracks can be air-pressure tested, so seam integrity is verified on site without destroying the weld.
Often yes. The hot wedge welder handles long production seams, while geomembrane glue and extrusion welding cover details, penetrations, patches and repairs where the wedge welder cannot reach. Most installations use the welder as the primary tool and glue for finishing.
The geomembrane welding machine price depends on the model, the welding power and the features specified, and a pond liner welding machine price varies the same way. We quote the machine to your project rather than list a single figure; published power, speed, voltage and weight ratings are issued on the SIGMA datasheet on request.
The hot-wedge welder runs on a mains supply and is rated for a defined power, voltage and temperature range, but those figures are model-specific and manufacturer-supplied rather than fixed by a public standard. Tell us your site supply and the liner thickness and we will confirm the right machine and its ratings on the datasheet.
The welding machine is sold as equipment, so the order can be a single unit; lead time depends on the model and current stock or build schedule. Send us your project dates and the liner type and we will confirm availability and delivery with the quotation.
Yes. The machine is crated for export and is commonly shipped with the geomembrane, pond liner and geomembrane glue for the same project, so the welder, the liner and the consumables arrive together. Confirm your destination and supply voltage and we will advise packing and any transport requirements.
