Abstract
An assessment of the residual stress pattern around a butt-weld has been made using a hole-drilling technique along with a sensitive moire fringe method. The method of applying the specimen grid is described, and also the procedures for extracting stress data from the moire fringe patterns. This technique may be useful in situations where the residual stress varies rapidly, or where it is inconvenient to apply numbers of strain gauges.
