HF Welding Technology in Large-Format Production
FIAB high-frequency welding machines are a solution created for manufacturers of large structures from thermoplastic materials. HF technology at a frequency of 27.12 MHz or 40.68 MHz ensures durable, hermetic welds on large surfaces, which are crucial in the production of tent halls, tanks, tarpaulins, and architectural membranes.
Applications in Large-Format Production
- Tent and storage halls – welding tarpaulin covers on steel structures
- Truck tarpaulins – production of covers for TIR trucks and trailers
- Flexible tanks – production of tanks for water, fuel, waste (up to 1000 m³)
- Architectural membranes – tensioned structures, pneumatic roofs, stretch ceilings
- Pontoons and boats – welding pneumatic structures
- Flood barriers – production of protective barriers
- Pools and pool liners – pool liners and covers
- Awnings and canopies – large-format shading systems
FIAB Models for Large Structures
FIAB 500, 860, 960 – mid-range machines with 5-8 kW power and electrode length up to 700-800 mm, ideal for medium production of tarpaulins and tent halls.
FIAB 1400 – premium series (13-26 kW) with electrode up to 1500 mm and welding area up to 750 cm². Available in mobile and stationary versions. Construction enabling welding "from the inside" facilitates handling of large-format materials.
FIAB 1400LS – quiet version for production halls with acoustic requirements.
FIAB 1900W and 2060W – machines with the largest working width for extremely wide structures.
FIAB HPS-MINI – mobile wheeled welding machine (8 kW, 400 mm electrode) with 180° rotating head. Ideal for on-site welding without material transport.
FIAB XYZ-SPIDER – movable head in 3 axes for welding spatial contours.
Advantages of HF Technology in Large-Format Production
- Weld strength – joints stronger than the base material
- Tightness and waterproofing – hermetic welds for tanks and structures
- Process speed – cycles counted in seconds
- Precision – parameter repeatability in serial production
- Adhesive-free technology – elimination of solvents and adhesives
- Aesthetics – smooth, even welds without visible joining marks
Materials for Large Structures
- Coated PVC (650-900 g/m²) – truck tarpaulins, halls
- Architectural PVC – structural membranes
- Polyurethane – flexible tanks, pontoons
- Layered composites – fiber-reinforced materials
Specialist Electrodes
- Lamellar electrodes – linear welds
- Tunnel electrodes – application of piping and reinforcements
