Abstract
In order to improve a weld monitoring device comprising an optical detection device for detecting a light emission of a welding plasma and generating a signal corresponding to the ultraviolet emission portion and also comprising an analyzing device for processing this signal and having at least one analyzing member for ascertaining those interruptions in the ultraviolet emission which exceed a predeterminable length of time, such that, in general, a documentation of a welding process with respect to the interruptions in the ultraviolet emission occurring thereby is possible without preliminary tests and this permits analysis following completion of the welding process, it is suggested that the analyzing device have a plurality of analyzing members, that the predeterminable lengths of time of the individual analyzing members differ from one another, that each analyzing member report each interruption exceeding the respective predeterminable length of time to a storage member and that each storage member retain the reported interruptions for a subsequent read out.
