Abstract
PURPOSE: To lower residual stress by using a low alloy welding electrode of hardness lower than that of base metals as padding metal for the surface layer in contact with corrosive environments.
CONSTITUTION: In the case of locally shaping off the defect part of a structure of low alloy steels, particularly Mn-Mo or Mn-Ni-Mo steels and repair-welding the same, 1W2 layers of the surface side in contact with corrosive environments are left and said part is welded with a welding electrode of the same component system as that of the base metals. Thence, the outside circumferential part around the repairing part is beforehand welded with a high-nickel-welding electrode, after which it is successively build-up welded toward the central part side by a nickel welding electrode or a stainless steel welding electrode. In this welding process, the hardened layer near the welding heat affected zone bond of the base metals is made into fine tempered martensite structure; in addition, plastic working is applied to the build-up welded metal near the welding boundary after the end of the welding, whereby residual stress is lowered.
