This report is continued from the previous work to obtain the optimum welding electrode which has an adequate composition for cast iron welding. Fe - (0-50) % Ni - (0-15) % Mn alloys simulated to the composition of cast iron weld metal were molten and cast into four kinds of molds to examine solidification temperature, tensile strength, shrinkage length and thermal expansion coefficient, as same as previous work. Because of the changing size of copper mold for examining tensile strength, the cooling curves of the tensile test specimens were changed as the similar curve to that of the implant test of cast iron pre-heated to 423K. From the results obtained in the present work, it is concluded that the adequate composition range of the cast iron weld metals is Fe - (36-40) % Ni - (6-8) % Mn. As for 30% penetration rate, these figures turn out Fe - (51-57) % Ni - (8-12) % Mn electrode.
