<P>PROBLEM TO BE SOLVED: To provide a welding method that controls a generation or development of a stress corrosion cracking (SCC) and also prevents a weld cracking, in a simple manner. <P>SOLUTION: In the welding method, a steel stock 1 is arc-welded by using a welding rod 2 formed of a nickel base alloy and a welding torch 5, wherein the welding rod 2 is rotated at high speed and fed in a welding pool 3 that is melted by an arc 6. Since a deposited metal 4 formed in the process is agitated by the rotation of the welding rod 2 until just before the solidification, the crystalline structure direction thereof is prevented from being oriented in one direction, thereby forming a solidification structure having a randomness in the deposited metal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
