High frequency welding Certain plastics with chemical dipoles, such as polyvinyl chloride (PVC), polyamides (PA) and acetates can be heated with high frequency electromagnetic waves. High frequency welding uses this property to melt the plastics for joining. The heating can be localized and the process can be continuous.

This is the same concept as induction welding.
