| Abstract: | Submerged-arc welding experiments of pipeline steel were carried out using two kinds of newly-developed welding wire with appropriate welding process. The welding joints were found to have the microsturcture of dominant acicular ferrite and good strength and toughness. Experiments showed that HIC properties of welding joints for the newly-developed wires can meet the requirements concerned. |
