Weldy WGW 300 Automatic Hot Wedge Geomembrane Welding Machine

The Weldy WGW 300 is a 1750 W automatic hot wedge geomembrane welding machine operating at speeds up to 8.5 m/min with a copper 80 x 45 mm hot wedge and mid-wedge temperature sensor, 1400 N maximum welding pressure, three large drive rollers for terrain grip and stability, 2 x 12 mm dual weld seam, 150 mm maximum overlap, direct temperature and air volume controls with bilingual display, Field-Kit travel roller configuration, and compatibility with HDPE, LDPE, LLDPE, TPO, FPO, CSPE, PE, and PP geomembranes from 0.8 to 2.5 mm – designed for automatic overlap seam welding on landfill containment liners, mine containment systems, aquaculture facility liners, irrigation infrastructure, and civil engineering geomembrane installations across Oman and the GCC.

Entry-Level Automatic Hot Wedge Geomembrane Welding for Civil, Mining, and Environmental Applications

Automatic hot wedge geomembrane welding is the standard seam production method for civil engineering liner installations – landfill containment cells, mine heap leach pads, reservoir liners, and environmental barrier systems – where the dual-track weld seam with pressure-testable channel between the two weld tracks provides both the seam strength and the quality verification capability that civil liner installation specifications require. The automatic machine controls wedge temperature, drive speed, and seam pressure mechanically throughout each weld run, delivering the parameter consistency that manual welding cannot provide across the seam lengths and sustained welding sessions of civil geomembrane liner installation programmes.

The WGW 300 is positioned as the entry-level automatic hot wedge geomembrane welder in the Weldy range – deliberately designed to be simple and robust rather than feature-rich and complex. Its electrical controls are intelligently arranged for direct operation: heating and motor are switched on and off with dedicated controls, temperature is set and monitored directly from the front panel display, and the bilingual English and Chinese labelling ensures that the controls are readable and unambiguous for the operator at the machine. The copper hot wedge with mid-wedge temperature sensor provides the thermal monitoring at the fusion zone that geomembrane seam quality depends on – with the sensor positioned in the middle of the wedge rather than at the heating element to measure the actual wedge surface temperature that the membrane faces contact during welding. And the three large drive rollers with 1400 N welding pressure provide the terrain grip that distinguishes the WGW 300 for deployment on the embankment slopes, uneven liner surfaces, and near-vertical inclines that landfill cell construction, mine containment installation, and civil embankment liner work regularly presents. For civil engineering contractors, environmental liner installation teams, mine construction companies, and aquaculture facility developers across Oman and the GCC who require a capable, accessible automatic hot wedge geomembrane welder for liner installation programmes, the WGW 300 provides the correctly specified entry-level machine at the Weldy accessible price point backed by Leister Group engineering.

WGW 300 Technical Capabilities and Geomembrane Welding Features

• Copper Hot Wedge with Mid-Wedge Temperature Sensor: The 80 x 45 mm copper hot wedge heats both geomembrane overlap faces simultaneously as it passes between them during machine travel – with the temperature sensor positioned in the middle of the wedge body rather than at the external heating element, measuring the actual wedge surface temperature at the point of membrane contact throughout the weld run. This mid-wedge temperature measurement provides more accurate process temperature data than element-based temperature sensing, enabling the control system to maintain the wedge surface temperature that the specific geomembrane material and thickness specification requires rather than maintaining a heating element temperature that may not reflect the actual wedge-to-membrane contact temperature under varying site conditions.
• 1750 W Heating Power at up to 8.5 m/min Welding Speed: The 1750 W heating system maintains the copper wedge at the 450 degree C maximum temperature across the full 0 to 8.5 m/min speed range – providing the thermal output required for adequate geomembrane fusion at the welding speeds that productive civil liner seam programme throughput demands. The 8.5 m/min maximum speed enables productive coverage of the seam network on medium and large civil liner installations within the programme time constraints that liner installation scheduling imposes on the geomembrane installation contractor.
• Three Large Drive Rollers with 1400 N Maximum Welding Pressure: The three-roller drive and consolidation system applies up to 1400 N of welding pressure to the seam zone – combining the mechanical grip of the large drive rollers with the consolidation pressure that effective geomembrane seam bonding requires. The large roller dimensions provide the traction surface area that maintains reliable machine travel on the uneven, loose, and inclined substrate conditions of active landfill cell construction, mine containment liner installation, and civil embankment liner work – where smaller rollers would lose grip or skip on the irregular membrane surface conditions that field installation presents.
• Stable Performance on Inclined and Uneven Terrain: The WGW 300’s strong drive rollers maintain machine travel and seam quality on inclines approaching the vertical – enabling productive automatic welding on the steep embankment slopes that landfill cell side walls, mine heap leach pad perimeters, and civil containment embankments present, where the ability to weld on steep inclined surfaces determines whether the total liner installation can be completed by automatic machine or requires manual welding on the slope sections of the liner area.
• 2 x 12 mm Dual Weld Seam with 150 mm Maximum Overlap: The dual weld seam configuration produces two parallel 12 mm weld tracks with an unwelded test channel between them – the standard geomembrane seam geometry that allows air pressure testing of the seam channel after welding for quality verification before the liner is covered. This testable dual-track seam is the civil liner installation industry standard for HDPE and LDPE geomembrane seam quality documentation, and the 150 mm maximum overlap provides the seam width capacity for the standard geomembrane overlap specifications of civil liner installation projects across Oman and the GCC.
• Direct Temperature and Air Volume Controls for Intuitive Operation: Heating and motor are controlled with dedicated direct-access switches rather than menu-based parameter navigation – enabling the operator to activate and deactivate the wedge heating and drive independently with clear, unambiguous controls that are immediately understandable without operating manual reference. Temperature and air volume are adjusted directly from the front panel with the display showing current values throughout operation. The bilingual English and Chinese labelling ensures that the controls are readable for the multi-national operator teams that civil construction and environmental liner installation projects across Oman and the GCC commonly deploy.
• Field-Kit Travel Roller Configuration: The WGW 300 is equipped with a Field-Kit travel roller configuration – the roller setup recommended for outdoor geomembrane field installation applications where the liner surface conditions, substrate irregularity, and terrain variation of active civil project sites require the travel roller configuration appropriate for outdoor deployment rather than the Indoor-Kit configuration suited for pre-assembly workshop use. The Field-Kit configuration ensures the WGW 300 is correctly set up for the terrain and surface conditions of civil geomembrane liner installation from the point of delivery.
• Eight Compatible Geomembrane Material Types from 0.8 to 2.5 mm: Compatible with CSPE, FPO, HDPE, LDPE, LLDPE, PE, PP, and TPO geomembranes from 0.8 to 2.5 mm thickness – covering the primary geomembrane liner materials specified for landfill containment, mine liner systems, reservoir and canal liners, aquaculture facility ponds, and irrigation infrastructure across Oman and the GCC within a single machine configuration. For PVC geomembrane welding, a steel wedge is required as a replacement for the standard copper wedge supplied with the machine.
• Simple and Robust Design for Civil Site Deployment: The WGW 300’s design philosophy prioritises operational simplicity and mechanical robustness over feature complexity – producing a machine that can be understood, operated, and maintained by operators at any experience level with automatic geomembrane welders, and that withstands the physical handling, environmental exposure, and continuous operation demands of active civil construction site deployment across the temperature, dust, and UV conditions of outdoor geomembrane liner installation in Oman and the GCC.
• 15 kg with Storage Box for Site Transport: At 15 kg with a storage box included, the WGW 300 can be transported by two operators to the liner installation location, carried along the seam by the installation crew as the welding programme progresses across the liner area, and stored in the provided case during site transit and between installation sessions – without the mechanical handling equipment that heavier automatic welders require for safe site mobility.
