IN-SITU MEASUREMENT OF OXYGEN IN WELDS BY NONDESTRUCTIVE NEUTRON ACTIVATION ANALYSIS

The quantitative determination of oxygen in discrete samples of metals or other materials by rapid, nondestructive, neutron activation analysis is now a widely used technique. With sufficiently large samples and the best of available equipment, oxygen concentrations can be accurately measured down to levels as low as 1ppm. It is shown that, with similar but somewhat more modest equipment, the same technique can be applied to the in-situ determination of oxygen in welds, down to levels of about 50 ppm. An intermittent, rather than continuous, procedure is preferred.
