Abstract
PURPOSE: To obviate the deposition of chrome carbides on the front layer part of the welding heat affected zone by decarburizing stainless steel to turn the surface layer part near the weld zone to a decarburized layer then performing welding at the time of welding stainless steel to itself.
CONSTITUTION: C amount above the solubility limit (0.03% or more) of austenite stainless steel 1 such as SUS304 is decarburized so that at the surface layer part near the weld zone it becomes below the solubility limit. Next, the portions between the weld zones composed of the decarburized layers 5 formed are welded by using weld metal 2. According to this method, the deposition of chrome carbides on the surface layer part of the welding heat affected zone 3 forming the decarburized layer 5 does not occur even if it is heated to a carbide deposition temperature range by welding heat cycle, thus the occurrence of stress corrosion cracking may be prevented.
