摘要：

This paper describes the technical features of four electro-optic sensors for the monitoring of arc welding. The energy released in the process determines the formation of a strongly radiative plasma in the interaction zone. The working principle of the prototype is based on the detection of visible, infrared and ultraviolet emission of the plasma. A discrimination algorithm has been found that allows the characteristics of the weld to be evaluated and to distinguish bad weldings from good ones. (C) 2001 Elsevier Science Ltd.
