A method is for testing the structural integrity of a metal joint such as a weld. The method includes applying stress to the metal joint, and measuring a resistance of a circuit including the metal joint during application of the stress to the metal joint. A structural integrity of the metal joint is determined by comparing the measured resistance with a baseline resistance.

Method and system for testing the structural integrity of a metal joint

A method of calibrating an impedance measurement device for measuring DUT impedance includes performing short calibration measurements using a short calibration standard to obtain short raw data; performing first shunt calibration measurements using a first shunt calibration standard to obtain first raw data, the first shunt calibration standard having known first resistance and unknown first inductance; performing second shunt calibration measurements using a second shunt calibration standard to obtain second raw data, the second shunt calibration standard having known second resistance and unknown second inductance; determining first and second complex impedances of the first and second shunt calibration standards by calculating the first and second inductances using the short, first and second raw data applied to a specific error model; and determining general error coefficients for an error model using the first and second complex impedances and the first and second raw data applied to a one-port calibration procedure.
