Method of testing and monitoring joint health

A method for non-destructive health monitoring of a joined component, comprising:

• supplying a first current between a first end of a first member of the joined component and a first end of a second member of the joined component;
• measuring a first voltage between a second end of the first member and a second end of the second member, wherein the first end of the first member and the first end of second member are situated opposite of at least one joint from the second end of the first member and the second end of the second member;
• calculating a first joint resistance of the at least one joint from the supplied first current and the measured first voltage;
• comparing the calculated first joint resistance to a predetermined minimum joint resistance;
• comparing the calculated first joint resistance to a predetermined maximum joint resistance, wherein the predetermined maximum joint resistance is greater than the predetermined minimum joint resistance;
• and
• outputting a result of the comparison, wherein the result is one of:
• a measurement error, if the calculated first joint resistance is below the predetermined minimum joint resistance,
• a failed joint, if the calculated first joint resistance is above the predetermined maximum joint resistance, and
• an acceptable joint, if the calculated first joint resistance is above the predetermined minimum joint resistance and below the predetermined maximum joint resistance.
