Hot air

Hot air is the technology where hot air is blown between layers of material through a nozzle and where rollers press the preheated surfaces together.

Advantages with hot air: 
+ Can be used for non-dielectric materials
+ Advantageously used as a complement to HF for finishing bigger structures and for patches

Disadvantages with hot air:
- Difficult or impossible to remake the weld if the result is not satisfactory 
- Requires a skilled operator
- Noisy process which creates hazardous fumes/gas and requires an evacuation system
- Does not work well on thicker materials (materials heavier than 1000 g/m²)
- Difficult to create welds that are air-, liquid-, and gas-tight
