Welding method and welding system for angle measuring antenna

Abstract

The invention provides a welding method and a welding system of an angle measuring antenna. The welding method comprises the steps of forming a round hole in the center of a circular red copper foil, forming a step matched with the round hole on the kovar alloy micro-strip end of a connector, and then assembling the kovar alloy micro-strip end of the connector with the center of the circular red copper foil by use of the step and the round hole and welding by use of an argon tungsten-arc welding method; the welding method comprises a welding time relay control device, an argon tungsten-arc welding power source, a welding gun and an argon bottle; the argon tungsten-arc welding power source is used for controlling the high-frequency arc starter of the welding gun by use of the welding time relay control device; the welding gun is communicated with the argon bottle. The welding method and the welding system of the angle measuring antenna have the advantages that the welding quality meets the design requirements, a welded metal and a composite material are not damaged, the process is simple and reliable, mass production operations can be realized, and the equipment operating cost is low.

Description

technical field [0001] The invention relates to a welding method and a welding system for a connector kovar alloy microstrip and a circular copper foil on a goniometer antenna, and belongs to the field of connection of dissimilar metal materials. Background technique [0002] The goniometric antenna is a part that is quite difficult to process, and the environmental use requirement is 290°C. The electrical conductivity and low expansion of metal materials and the electrical insulation and temperature resistance of composite materials are comprehensively considered in the structural design. Therefore, the electrical conductivity Good copper foil (thickness only 0.5mm), low-expansion kovar alloy connector which is not sensitive to temperature, and PTFE composite material with high temperature resistance and good insulation. In order to ensure reliable connection and normal operation of the equipment in an environment of 290°C, the antenna connector and the copper foil are conn...
