Abstract

In the case of the laser welding control by means of the infrared thermographs, the information concerning the quality of the weld is obtained by using a temperature-measuring sensor at a specific point on the welding surface. In order to obtain good efficiency of the laser welding control, the point of the temperature measurement has to be chosen properly. In the present study, an attempt was made to determine an optimal position of the temperature sensor on the welding surface on the basis of comparative analysis of surface temperatures, which were obtained from experimental measurements and model calculations. It refers to laser welding of steel plate sheets.
