An apparatus and method for testing the structural joints in steel buildings is described. The invention provides electromechanical test units fixed at the joints of a building and permanently wired to a test apparatus such as an ultrasonic test monitor. Such a monitor may be one of many that are in communication with a central monitor and test management computer so as to accomplish wide spread testing of many buildings immediately after an earthquake by remote access.

[ What is claimed is:] [1.] A weld integrity inspection and evaluation apparatus for anticipation of weld failure not dependent upon external loads or forces for identifying structural weld failures, thus comprising:a plurality of electromechanical transducers, each electromechanical transducer being permanently joined with selected structural welded joining means;a plurality of electrical signal transmission means, each means being capable of electronic communication with each electromechanical transducer for transmitting a testing signal to an electromechanical transducer permanently mounted at each predetermined structural weld joint and for transmitting test results rebound signals from an electromechanical transducer back to a test signal generator and test results interpretation and display means;a test signal generator and test results interpretation and display means interconnected with a plurality of electrical signal transmission means;wherein each electromechanical transducer is enabled to receive and return predetermined electronic waveform patterns to ultrasonically test a structural weld for anticipation or for identification of weld failures without external load or force.
