Effects of Chemical Compositions of the Submerged Arc Welding Wires on Impact Toughness of the Weld Metals for the Pipeline Steel

Abstract:

With the development of high toughness pipeline, it is necessary to develop new welding wires for high-efficiency submerged-arc welding, to produce weld metals whose properties can match corresponding ones of the base metal, such as strength, toughness, H2S corrosion resistance, etc. In this paper, the weld wires with variations of elements have been designed, and the effects of alloy elements on the microstructures and low temperature impact toughness are discussed.
