Here is a short informational note on what is called hot air welding. There are numerous applications to which this process could be applied. And each industrial complex to its own, different approaches could be taken, rf welding being just one example for now. Hot air welding entails a heat sealing process. It will be applying heat and pressure to a number of material pieces. This is done either through a rotary press or manually.
The object of the exercise is to create a permanent seal. This seal becomes resistant to air and water pressure. The sealing process is ideally suited to the fabrication of products and for improving their functionality. This is because the bond created will be stronger than any original materials used during the fabrication process. There are a number of benefits to hot air welding that override those of alternative heat sealing processes.
Hot air sealing will take a lot quicker to accomplish than radio frequency welding. It is ideally suited for fabrications of three-dimensional products. This welding process does not require the use of tools or dies. But at the same time, just like hot wedge sealing, only two surfaces can be sealed at any one time. The hot air sealing process is able seal a greater number of materials than alternative sealing processes. It is also able to form long and continuous panels.
It is perfectly suited for the manufacture of larger products such as containment and inflatable products, as well as products that require curved seams. The heat sealing process allows for freehand sealing owing to its ability to adapt to maneuvering motions and the approach of bonded materials. Hot air welding does not require wedges to be formed during the heating process.
