| Abstract: | In this paper the relations between structure , toughness and cold cracking susceptibility of HAZ(heat-affected zone) for steel 2.25 Cr-1Mo have been quantitatively analyzed using methods of thermal simulation test and implant test. The welding procedures were pointed out for both avoiding cold cracking and improving toughness of HAZ. |
