Summary: The thermoelectric power coefficient is introduced as an electronic property that can be measured to assess weld microstructure, phase stability, interstitital solute content, residual strain (stress), and properties. These weld properties can be correlated to the thermoelectric power coefficient using a nearly free electron model description of the electronic state of an alloy. Examples of such correlations are described.
