What is Hot Air Welding?

HubSpot Video

A hot air welder uses very precise heat, speed, and pressure to join thermoplastic industrial fabrics and films. The correct combination of these three parameters achieves a complete weld on an application. The hot air welding process compresses and blows air across electrical heat elements to apply and inject that heat at the welding point. The tightly controlled temperature ranges from 700°F to 1,350°F (400°C to 730°C).

Is Hot Air Welding Right for My Application

To ensure our customers have the best heat system for their application, it is best to speak with a Miller Weldmaster expert. While hot air, hot wedge, impulse and RF work for many applications, one may work better than the other depending on the application. Miller Weldmaster will help you select the best technology for your application.

Why choose Hot Air Welding
  • Constructing a product with different shapes and curves
  • Producing a versatile range of products
  • Create seams that are stronger than the material itself for diverse manufacturing jobs
  • Create airtight and waterproof seams unlike when you sew and are poking holes in the fabric
  • Changing the weld width often throughout the manufacturing process
  • Using multiple welding heads simultaneously
  • Starting and stopping often throughout the welding process
