High Frequency Application - SEIDENSHA - Welding & Cutting ...
High-Frequency Application. High-Frequency Application refers to both direct application of high frequency energy to a material (radio frequency welding/cutting) and indirect heating through induction in a separate ferromagnetic material (induction welding, hot plate welding). The principles of these applications are very similar.
High-Frequency Ventilation – Basics and Practical Applications
High-frequency ventilation (HFV) as a ventilatory therapy has reached increasing clinical application over the past ten years. The term com-prises several methods.
