Abstract

PURPOSE: To prevent the strain ageing embrittlement of weld bond part at the butt welding method of low alloy steel by carrying out the build up welding on the weld zone of the last layer and making the coarse crystalline grain minute.
CONSTITUTION: The coarse crystal grain 4 is left on the base material neighboring the weld boundary by the thermal influence of the last weld layer 3, on occasion of carrying out the butt welding 2 of the low alloy steel 1, such as Mn-Mo alloy. The build up welding 5 of maximum 80% for the width of the last weld bead, is carried out on the last welding layer 3 moreover, in order to make the coarse structure 4 minute. thus, embrittlement by the strain aging is prevented by improving the toughness.
