Product Name
Leister 146.247 Welding shoe complete (FWP-Ext. Air) V-Seam 30mm
Brief Description
This product is an essential accessory for Leister extrusion welders, specifically engineered to create robust 30mm V-seams in various thermoplastic materials. It is designed for use with extrusion welders that feature an external air guide for efficient preheating of the welding surface, ensuring strong and consistent welds in thick plastic fabrications.
Popular Applications & Uses
- Welding thick-section plastic fabrications, including tanks, pipes, and fittings.- Joining lining materials for environmental applications such as landfill waste sites, lagoons, and roof coverings.- Utilized in boat construction and repair.- Manufacturing of fume hoods, ducts, and other large plastic components.
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services- Chemical Industry- Marine- Energy (specifically for environmental and water engineering applications)- General Manufacturing
Special and Unique Features
- Specifically designed for V-seam welding, which is ideal for creating strong butt welds on thicker plastic materials.- Produces a substantial 30mm weld width, contributing to robust and durable seams.- The "complete" designation indicates it is a ready-to-use component for compatible Leister extrusion welders.- Features an external air guide, facilitating efficient preheating of the welding surface for optimal material fusion.- Enables the production of long and consistent welded seams in a single pass, which translates to shorter processing times and increased efficiency.
Key Properties
- Part Number: 146.247- Brand: Leister- Welding Seam Geometry: V-seam / X-seam (a V-seam is a type of butt weld, and an X-seam is a double-V seam)- Weld Width: 30mm (1.2 inches)- Air Guide: External- Compatibility: Designed for Leister WELDPLAST S2 PVC, WELDPLAST S4, WELDPLAST S6, WELDPLAST 600, and WELDPLAST 605 series extrusion welders.
Surface Compatibility
- Compatible with various thermoplastic materials, including Polyethylene (PE), Polypropylene (PP), Polyvinyl Chloride (PVC), and PVDF.- Particularly effective for joining thicker plastic materials, typically greater than 6 mm in thickness.
Known backups / known substitutes
- Other Leister welding shoes offering different seam geometries (e.g., fillet weld, overlap, corner seam) or varying sizes (e.g., 20mm, 25mm, 40mm).- Blank welding shoes are available for custom shaping to meet specific application requirements.- While direct compatibility is unlikely without adapters, welding shoes from other manufacturers of plastic extrusion welding equipment could be considered as alternatives.
Comparison Note
This 30mm V-seam welding shoe is specifically optimized for creating strong, deep V-shaped butt welds in thick plastic materials. It offers significant advantages over traditional hot gas welding methods in terms of bond strength and processing speed for large-volume projects. Its V-seam geometry provides a distinct advantage over other types of welding shoes, such as fillet or overlap welds, making it particularly suitable for applications that demand a robust, full-penetration joint in specific material thicknesses and configurations.
