Effects of Submerged Arc Weld (SAW) Parameters on Bead Geometry and Notch-Toughness for X70 and X80 Linepipe Steels
DownloadFall 2009
For the manufacture of higher strength pipelines to be feasible, a better understanding of the effects of welding on toughness is necessary. Bevel submerged arc welds were performed on X80 grade steel. The subsequent Charpy V-notch (CVN) test results indicated that the notch placement in the...

It is difficult to join high strength alloy steel which are produced by thermo mechanical controlled processing and get overmatched properties on the welds and heat affected zone (HAZ) when submerged arc welding (SAW) is used as joining process. Circumferential welds made in the mill to join...
