Abstract
A preliminary investigation was conducted to explore the applicability of an eddy current nondestructive evaluation technique to the characterization of residual stresses in a low alloy, heavy section steel weldment. Simulated weld repair samples were examined with a hand held eddy current probe and the results correlated with strain gage measurements of residual surface stresses. Eddy current measurement profiles were used to estimate residual stress contours. The advantages and potential problems associated with an eddy current approach to the measurement of residual stresses are discussed.
