Однако оно не обеспечивает This device allows to heat the parts to be soldered in hard-to-reach places by means of a long steam rod, prefilled the heat pipe itself, since its thermal conductivity exceeds the thermal conductivity of copper rods by a factor of ten times and the end temperature; The tubes practically do not differ from the temperature at the beginning of the tube with a considerable range of heat transfer. However, it does not provide

This device delivers ultrasonic vibrations to the soldering zone without an external high-frequency generator with significant lengths of the solder rod. However, the single-vibration oscillations generated in this device by ultrahigh-frequency electrons are completely shielded by the walls of the PA Yalnog rod and do not act directly on the soldering parts. At the same time, this effect would be useful, since electromagnetic waves of high frequency allow to increase the speed and increase the quality of the soldering, making it difficult to weld parts, such as aluminum waveguides and resonators of aircraft radar stations, due to the skip effect. The aim of the invention is to increase the speed and improve the quality of soldering the work of nospaimaya parts by acting on the soldering zone of ultrahigh-frequency electrodynamic oscillations. This is achieved by the fact that the proposed device is equipped with an electrolytic wave chatted therein, installed in the form of a glass, installed in a tube with an annular gap connected to the side wall with a delay line, and with an end wall with the outer surface of the tube.
