Product Name
- Leister 145.811 - Complete (FWP-Int.Air) corner long, D=0.5" Welding Shoe for Fusion 1 welders
Brief Description
- The Leister 145.811 is a precision-engineered welding shoe, also known as a welding tip, specifically designed for creating corner seams with internal air guidance. It is an essential accessory for Leister Fusion 1 extrusion welders, and compatible with other Leister Fusion and Weldplast series extruders, facilitating high-quality plastic welding in various applications.
Popular Applications & Uses
- Plastic fabrication, including tanks, containers, and apparatus construction.- Welding connection nozzles and pipe junctions.- Repair of plastic components and structures.- Waterproofing applications such as pond liners, reservoirs, canals, and landfill membranes.- Construction and repair in aquaculture and boat building.- Ideal for welding in tight, restricted, and hard-to-reach spaces due to its design and the compact nature of the Fusion 1 welder it supports.
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services (for geomembrane welding, waterproofing, pipe, and tank construction)- Marine (for boat construction and repair)- General Manufacturing (for general plastic repairs and container fabrication)
Special and Unique Features
- Specifically designed for corner seam welding geometry.- Features an internal air guide (FWP-Int.Air) for optimized heat distribution during the welding process.- Optimized for use with Leister Fusion 1 extrusion welders, known for their compact design and maneuverability in confined spaces.- Precision-machined to ensure consistent and high-quality welds.
Key Properties
- **Welding Seam Geometry:** Corner seam.- **Air Guide:** Internal.- **Diameter:** D=0.5" (approximately 12.7mm, often referred to as 14mm in some contexts for this part number).- **Compatibility:** Designed for Leister Fusion 1, and compatible with Leister Weldplast S2, Fusion 2, Fusion 3, and Fusion 3C extrusion welders.
Surface Compatibility
- This welding shoe is used for welding various thermoplastic materials, including but not limited to:- High-Density Polyethylene (HDPE)- Low-Density Polyethylene (LDPE)- Linear Low-Density Polyethylene (LLDPE)- Polypropylene (PP)- Thermoplastic Polyolefin (TPO)- Flexible Polyolefin (FPO)- Also suitable for materials like Acrylic, PVC Foam, and Polycarbonate when used with compatible Leister extruders.
Known backups / known substitutes
- **Other Leister Welding Shoes:** Leister offers a range of welding shoes for different seam geometries (e.g., fillet weld, V-seam, overlap weld) and sizes, such as the 145.812 (15mm fillet welding shoe) or 146.645 (10mm corner outside seam shoe).- **Blank Welding Shoes:** Leister also provides blank welding shoes (e.g., 146.239) that can be custom-machined by the user to fit unique or specialized welding requirements.- **Third-Party Welding Shoes:** Welding shoes from other manufacturers like HSK, WEGENER, Munsch, or Ritmo America may serve as substitutes if they are compatible with Leister extruders or if alternative extrusion welders are used.
Comparison Note
- The Leister 145.811 welding shoe stands out due to its specific design for corner seams with internal air guidance, making it highly effective for precise work in challenging geometries and confined spaces. While other welding shoes exist for different seam types (fillet, V-butt, overlap) or external air guidance, this particular model is optimized for the unique requirements of corner welds, especially when paired with the agile Leister Fusion 1 extruder. The Leister brand is recognized for its Swiss engineering and quality in plastic welding technology.
