Radio frequency welding, also known as RF welding, dielectric welding, or high frequency welding, is the process of fusing materials together by applying radio frequency energy.

Radio frequency welding is used to join or assemble various thermoplastic materials such as PVC (polyvinylchloride), polyurethanes, and others. The resulting seam is impervious to fluids as no needle holes are created. Manufacturers of healthcare, medical, industrial and consumer products alike use radio frequency welding to produce products where a strong fluid proof  or hermetic seal is needed.
