RF welding is a technology enabling and the basic equipment necessary to affect these joints changed since the inception of this process. Today, as in 1942, we have the RF generator, transmission line must make available to transmission, to apply for a press conference about violence and the electrodes to the desired geometric patterns are welded.

The term “radio frequency (RF) welding or sealing is often used interchangeably with” high-frequency (HF) or dielectric welding and sealing. When a case is in contact with the electromagnetic field through a portion of the electromagnetic field is a change of energy state. As a result, it is converted into heat and dissipated in contact on this matter. The extent to which they are con-version, or energy conversion efficiency of this state depends on the atomic and molecular structure of matter, the frequency of the electromagnetic field and potential field (Volt-age/cm). The term dielectric heating correctly describes this phenomenon in the frequency, or RF during RF heating describes the process, the limited frequency range 100-200 MHz / s (Mega Hz / s).

The area where most of the technological changes have taken place in part, from which the individual units to be built. semiconductor rectifier to replace mercury vapor lamps. Digital Timer Timer industrial replaced. Programmable logic controllers (PLCs) have replaced the relay logic.

If the PLC control system with linear optical and coded, the control of different functions in order to determine the specificity of the weld can be achieved. With this type of equipment it is possible to monitor and control function of time, pressure, current and voltage and their profiles.

can be used as a modern material handling systems associated with these devices, the rapid automated production lines are built. Hundreds of such systems are applied throughout the U.S. These systems are a variety of products for automotive, stationary products and medical technologies.

Still influx of new materials RF responsive to the market brought further impact on the industry. In addition to the response, additives and adhesives RF are constantly being developed for specific applications. It is now possible to bond materials, which in the past as unsuitable for the process of RF. These changes include opening a new range of products that can now be produced in this time-proven technologies. This will be a major impact in the medical industry as it tries to eliminate the use of vinyl.

Both the electron beam and laser welding, where he first discovered to be possible to exchange technologies. However, these technologies tend to be found on the spot or seam welding of metal or other rigid materials for which welding time in minutes and hours are measured. RF welding, welding time are measured in seconds, or fractions thereof. Guidelines believes that the probability that it is always competing technologies is very low. The guidelines for the opinion there is nothing on the horizon to replace the RF-welding in the next 5-10 years. His place will be as safe as it is today, not only economically preferred method of welding of certain materials, but in many cases the only practical.

U.S. companies most likely major players 10-20 years into the future Hall Dielectric THERMEX Machine Co. and Therma-Tron Inc. Both companies are deeply in their engineering and technical staff, the basic old, experienced technical specialists with a good combination of young talent behind them is prepared to take initiative.
