What Is Hot Air Welding?

Every type of material joining has an optimal joining method. For certain materials with thermoplastic coatings, hot air welding is a simple, fast and affordable solution. Hot air welding uses heated air to begin to melt the mating surfaces of the two materials you are looking to join. Pressure applied from a system of rollers — or manually, in certain cases — combines with the heat to form an extremely strong bond.

Hot air welding is a popular joining solution for several reasons:

  • You can join long, continuous panels
  • You can join a variety of materials of the same thickness
  • The resulting joint is stronger than the parent material
  • The seal is watertight and airtight
  • No special tooling or dies are required

The various uses of hot air welders means the process can be adapted to the size and shape of your materials. Even complicated shapes and contours can be hot air welded with a manual process, eliminating the need for costly tooling investment. Don’t adjust your product to meet the constraints of a joining method. Instead, choose a versatile welding process, such as hot air welding, that suits your requirements in terms of strength, durability and cost.

Multiple Uses for Hot Air Welders

Hot air welders are used to fabricate a variety of products, including:

  • Industrial curtain walls
  • Tarpaulins and large paneled products
  • Complex shapes with curves and cutouts
  • Sealed air hoses
  • Fluid-containment bags
  • Industrial fluid overflow bags

Hot air welders allow for versatile joining of complex shapes. We can even adjust our hot air welders to accommodate a change in seam width along your seam. That kind of flexibility makes hot air welding a popular choice for a wide range of industrial and commercial thermoplastic-coated materials. You can join materials such as:

  • Polypropylene
  • Polyethylene
  • PVC coated fabrics
  • Synthetics
  • Olefin
  • Nylon
  • Thermoplastic films
