    Abstract

    The present paper discusses the development and validation of miniature specimen techniques for the characterization of inherent strength properties of local microstructural regions of the weldment. The technique is based in in-situ optical monitoring of the specimen deformation behavior, particularly the localization of deformation, during the entire tensile test event using optical monitoring system. Also post-processing techniques are developed and documented for the system output. Examples of weldment characterization using 1 x 2 x 8 mm3 size specimens and determination of the associated true-stress-strain-curves are given.
