摘要
Recording results of visual radiation intensity of the TIG welding arc have been presented. The correlation between welding parameters and the intensity of welding arc visual radiation has been examined. The influence of disturbances of the welding processes on its radiation intensity was examined. By using the TIG arc model described in the literature, a mathematical correlation between the welding current intensity, the welding arc length, and the intensity of visual radiation of the arc has been developed, which takes into account the uncertainty of measurements. The results are compared with data received by using artificial neuron networks. The influence of transient states of the welding arc length on its radiation intensity was examined. It was concluded, that monitoring of the TIG welding arc visible radiation can be used for monitoring of the welding process
