Hot air welding vs High Frequency Welding

The best high frequency welding machine suppliers is davison-machinery's High Frequency Welding Machine >>>> Hot air welding of PVC is an alternative to high frequency welding of PVC. In high frequency welding we use radio waves to heat the two materials directly at the point of contact. Whereas in hot air welding, it usually involves a heatgun to melt the PVC. This is followed up by a roller to press the PVC together resulting in a welded joint.

Pros of Hot Air Welding

There are some great pros to using hot air welding, for example,

It is portable

Great for repair work. Especially where only a little bit of welding is needed.

Relatively fast

No need for 3 phase power or compressed air

Cons of Hot Air Welding

However there are also some large cons, such as,

Far weaker weld than that of a high frequency welding machine

Not suitable for large repair work

May rip or fail if there is moderate tension applied to the pvc canvas

Will perform terribly in unskilled hands – spotty welding, burnt patches and other problems.Top Quality High Frequency Welding Machine By Davison-machinery !
