The permitted frequencies for plastic welders are 13.56, 27.12, or 40.68 megahertz (MHz). The most popular industrial frequency for HF welding is 27.12MHz. The radio frequency fields from a plastic welder spread out around the machine, but most often it is only right next to the machine that the field is so strong that precautions need to be taken.
Welding diodes. Welding diodes are designed for medium and high frequency welding equipment and optimized for high current rectifiers. The on-state voltage is very low and the output current is high. Hitachi Energy is selling both normal housed and housing-less welding diodes. The latter is becoming more and more important in high current

Medium frequency welding. With inverter power sources, the welding transformer is fed with an alternating voltage of about 1 kHz to 4 kHz (medium frequency) or about 20 kHz (high frequency). The significantly greater control speed is advantageous (with 1-kHz inverters, a power controller response time of 0.5 ms is achieved compared to 10 ms
From the top view of energy distribution (Fig. 5 (a), (b) and (c)), the central area presented adjacent distribution of peaks and valleys when the frequency was 100 Hz; while the energy distribution was more uniform near the weld centerline when the frequency was
RF welding, also called high-frequency welding or sealing, heat sealing, and dielectric welding or sealing, uses high-frequency (13–100 MHz) EMA energy to generate heat in polar materials, resulting in melting and weld formation after cooling. A high-intensity radio signal is used to impart increased molecular motion in two similar or

According to the pulse frequency, pulse current can be divided into low frequency (less than 100 Hz), medium frequency (100–1000 Hz), and high frequency (more than 1000 Hz). Xu et al. [ 21 ] measured the maximum arc width at pulse frequencies of 2–15,000 Hz and obtained a natural logarithm relationship curve with the pulse current
There are three types of AC power used in induction furnaces: power frequency (50 Hz or 60 Hz), medium frequency (60 to 10,000 Hz) and high frequency (above 10,000 Hz). Components. The main components of an induction furnace include inductors, furnace bodies, power supplies, capacitors and control systems.
