The purpose of this report is to conduct various investigations and examinations for the improvement of impact characteristics of ES weld metal using different types of welding wire. In this experiment, six types of welding wire are used by changing welding heat input to three levels such as Q=456,790 and 1,207KJ/cm. The summary of the test results obtained are as in the following. (1) In the case of all three heat input levels, the impact test value in center location (C) of ES weld metal is generally lower than those in perifery locations (R). Furthermore, regardless of the types of welding wires, the same tendency has been noticed. (2) The possibility to improve the EA value in C location of weld metal which has been produced in the standard heat input such as Q=456KJ/cm using Ni containing wire is found.
