| Abstract: | During the manufacture process of heavy pressure vessel with 2.25Cr-1Mo steel barrel body,there will be use the welding process between 0Cr18Ni9 stainless steel internal structural parts and 2.25Cr-1Mo steel shell ring.The relevant process elements for welding this different kind of steel by adopting the Fuse Core Arc Welding have been described.By means of test,how to adjust the process in order to improve the situation which is easy to appear the embrittlement structure at the welding joint has been analyzed,in order to satisfy the product design requirement for property of welding joint. |
