Abstract
A process for the control and/or guidance of welds in electric arc welding wherein a metal or a metal alloy is applied to the edge or surface to be welded of at least one workpiece, with the metal or at least one of the principal alloying metals not being present in the workpiece or at least in slight proportions only, so that a characteristic spectral line emitted by at least one of the metals applied is observed spectroanalytically in the arc and that the weld is controlled and/or the arc guided by means of the spectral data determined.
