Abstrakty
Przedstawiono fizyczne podstawy bezstykowych pomiarów temperatury oraz oceną możliwości wykonania ciągłego pomiaru temperatury w linii technologicznej zgrzewania, z uwzględnieniem analizy metod pomiaru. Zamieszczono wyniki badań temperatury w strefie oraz linii zgrzewania za pomocą pirometru i kamery termowizyjnej.
The paper presents the analysis of temperature measurement, evaluates the possibilities of continuous temperature measurement on process lines and the determination of temperature distribution. Tests were made during welding smooth and perforated pipes with Alusi coatings. The results of the temperature measurement helped to determine the working point of the line, i.e. the selection of optimum values of each process parameter. In the case of continuous measurement the results are used to control the process. The Information about the thermal field, its distribution along the circuit and the welding line can also be of interest, especially for the thermal flow area (SWC), where structural changes not only in the weld but also in its vicinity are observed. Pipe cracking outside the weld can be the result of this phenomenon. In order to make control of the SWC possible we should aim at gaining the best possible knowledge about the process. Tests covered continuous measurements of the maximum temperature in the welding area (the point where two edges of the open-joint tubes are in contact with each other) with a pyrometer placed in the line and observations with an infrared camera which were to determine the thermal field.
