A theoretical study of electrical characteristics of metal to metal adhesive bonded joints, with emphasis toward developing a satisfactory non-destructive test to determine quality of the bond, is presented.nTo supplement the theoretical study, three types of experimental tests were conducted on adhesive bonded joints fabricated under close laboratory control. These tests were:n1. sonic - employing a "sonizon", a commercial resonancentype instrument.n2. capacitance - using an impedance bridge at 100 kilocycles.n3. d.c. resistance - using a standard ohmmeter.nThe results indicate that more extensive research on electrical characteristics of adhesive bonded joints must be conducted to establish definite correlation to bond quality.
