PURPOSE:To prevent generation of stress corrosion cracking in a weld zone in the stage of welding an austenitic stainless steel and a carbon steel by beveling much the edge on the austenitic stainless steel side. CONSTITUTION:The edge on an austenitic stainless steel side is beveled much and welding is so accomplished that the angle theta (acute angleABB') at the junction point B of a carbon steel 2 and a deposited metal 3 attains <=90 deg. in the stage of welding different metallic materials such as the steel 1 and the carbon steel 2 from one side by using a welding rod of an austenitic stainless steel or an inconel welding rod. The stress corrosion cracking in the joint part between the austenitic stainless steel and the carbon steel is prevented. |
