Abstract

The article suggests the use of indirect measurements to control the process of induction soldering. Based on the equations of thermodynamics, it is proposed a scheme for approximating the temperature values in the solder zone on the basis of information from pyrometric sensors aimed at an area remote from the soldered joint site. A model-algorithmic instrument for indirect temperature measurements in the soldering technological process is developed, the scheme of which is presented in the article. The software of waveguide paths induction soldering control in the form of an already existing system module has been developed, which allows not only to carry out experimental studies on control algorithms, but also to implement a full-scale experiment, the results of which confirm the effectiveness of the proposed approach.

Highlights

In the aerospace industry, rigid restrictions on the mass of aircraft cause the use of various elements of payload modules with optimal mass-size characteristics
It is expedient and relevant to use in the information control system indirect temperature measurements which are made at a distance spot from the solder zone
The article describes in detail the technological process of waveguide paths soldering using induction heating, as well as the main problems associated with its use

Summary

Introduction

Rigid restrictions on the mass of aircraft cause the use of various elements of payload modules with optimal mass-size characteristics. This applies to waveguide paths of antenna-feeder devices of space vehicles. In the process of induction heating control, when forming soldered joints of waveguide paths, it is required to measure the process temperature, for which the use of pyrometric sensors is best suited [3, 4]. It is expedient and relevant to use in the information control system indirect temperature measurements which are made at a distance spot from the solder zone
