The Bureau of Mines and the Eaton Corporation are using capacitive-discharge welding (CDW) to explore the thermal and microstructural behavior of rapidly solidified weldments. CDW experiments were conducted using 1080 eutectoid steel rods as the cathode and anode. In addition, dissimilar metal tube welds were made with 6061 aluminum tubes as the cathode and mild steel sheets as the anodes. In conjunction with this experimental work, finite element models were developed for rod-to-rod and tube-to-shell geometries. These models allowed the direct calculation of solidification parameters (G-R and G/R), weld and heat affected zone thicknesses, and metal loss during the CDW event. Metallurgical observations correlate well with the finite element analyses.
