A two-body single-turn electrode for high-frequency welding

Abstract

The present invention proposes a two-body single-turn electrode for high-frequency welding, including an outer electrode and an inner electrode. For the workpiece to be welded, the inner electrode is arranged inside the outer electrode and connected to the inner wall of the outer electrode. When welding workpieces with different diameters, the matching inner electrode can be replaced on the outer electrode. The invention adopts a split structure, which is convenient for disassembly and installation, and has a reliable structure.

Description

technical field [0001] The invention relates to a single-turn electrode for high-frequency welding, in particular to a two-body single-turn electrode for high-frequency welding. Background technique [0002] Traveling wave tube is the core device of microwave power amplification, and is widely used in radar, electronic countermeasures, communication and other fields. High-frequency welding is an important link in the processing of components such as energy transmission windows in traveling wave tubes. The quality of welding directly affects the airtightness of products. At present, the electrodes used for high-frequency welding are all one-piece structures, which have defects in welding quality, welding efficiency and safety. The specific performance is as follows: [0003] (1) The heat-affected zone of welding is still relatively large, which is easy to cause cracking of the ceramic adjacent to the ceramic-metal sealing part, or air leakage in the weld seam of the sealing ...

AI Technical Summary

Problems solved by technology

[0003] (1) The heat-affected zone of welding is still relatively large, which is easy to cause cracking of the ceramic adjacent to the ceramic-metal sealing part, or air leakage in the weld seam of the sealing part;

[0004] (2) Only one type of workpiece can be welded without replacing the electrode. In order to meet the welding of workpieces with different diameters and specifications, the original electrode needs to be removed each time, and then the corresponding electrode that matches the diameter of the workpiece can be installed. In the mass welding process of engineering application, the welding efficiency is extremely low;

[0005] (3) Repeated replacement of the electrode will result in poor sealing effect of the connection between the electrode and the equipment, manifested as water leakage or sparking, and there are certain hidden dangers of failure
