Abstract

This report describes a prototype system developed by the U. S. Army Construction Engineering Research Laboratory for real-time, in-process weld quality control. The system uses weld-arc spectral analyses done by an electro-optic detection device. The results of this study indicate that it may be possible to monitor many flaw-inducing conditions such as loss of shielding gas, loss of flux, and hydrogen embrittlement by observing specific regions of the arc spectra. This report also describes the design and initial tests of a microprocessor control spectrograph.
