Abstract: To test certain structural characteristics of a weld formed between two dissimilar metals in order to test the quality, or structural integrity, of the weld, the emf generated at the weld bond interface during welding, as a result of the Seebeck effect (thermocouple), is monitored. As the weld cools, the emf decreases at a first essentially rapid rate with respect to time until the weld begins to recrystallize, or fuse, at which point the emf decreases at a second and slower rate since the latent heat of fusion of the metals decreases the cooling rate of the weld. When recrystallization is complete, the emf decreases at an essentially exponential rate. It has been discovered the rate of change of the emf with respect to time during recrystallization is an indication of the quantity of the metal involved in the weld where the weld is exposed to a constant heat sink, such as the atmosphere, since the more metal that is involved in the weld the slower the weld will cool during fusion, and vice versa.

A transducer senses axial displacement of the shaft such that the magnitude of the shaft displacement is related to the stress in the sample. The sample may be subjected to temperature variations during the test cycle.
