Microscopic survey, measurement of grain size and electron probe microanalysis of Fe-Ni, Fe-Cu, Fe-Mn and Fe-C weld metals were performed.<BR>The results obtained are summerized as follows;<BR>(1) In Fe-Mn, Fe-Ni and Fe-Cu weld metals, the solidification structure changes from equiaxed to columnar crystal and still to cell structure with increasing the contents of alloying elements.<BR>(2) In Fe-C weld metals, the solidification structure changes from equiaxed to columnar crystal with a small amount of carbon.<BR>(3) The segregation of alloying elements are observed in the cell boundaries.<BR>(4) The solidification structure of the weld metals is disarranged by peritectic reaction.<BR>(5) The concentration gradients of alloying elements are observed in the weld metals of 26 to 108 μ width near the fusion lines.<BR>(6) The alloying elements appear to diffuse into unmelted base metal about 5 to 10 μ.<BR>(7) The macroscopic segregation of alloying element is observed only in Fe-Ni weld metals.
