摘要： Disclosed is a method for the nondestructive testing of weld clusters having at least a first and a second weld joining metal elements including the steps of injecting a current into one of the elements from a suitable source by contacting each of the elements with a current probe therefrom. A first current density is then measured between the current probe and the first weld and a second current density is measured between the current probe and the second weld and the first current density is then compared with the second current density so as to determine the relative quality of said welds.
