Effect of cold wire addition in tandem submerged arc welding on weld geometry and micro-hardness of heavy gauge X70 steel
Download2022-01-01
Ren, T., Mohammadijoo, M., Wiskel, J.B., Lazor, R., Willett, E., Ivey, D.G., Henein, H.
The pipeline industry has undertaken an essential upgrade of well established X70 pipeline steel in heavy gauge pipes to fill the demand of increased operating pressures. A developed welding process, cold wire tandem submerged arc welding (CWTSAW), with improved deposition rate and travel speed...

Influence of Cold-Wire Tandem Submerged Arc Welding Parameters on Weld Geometry and Microhardness of Microalloyed Pipeline Steels
Download2016-01-01
Mohammadijoo, M., Henein, H., Collins, L., Ivey, D.G.
Tandem submerged arc welding with an additional cold wire (CWTSAW) is being developed for pipeline manufacturing to improve productivity in terms of deposition rate and travel speed of welding. An appropriate understanding of the welding conditions to guarantee requisite weld geometry, appearance...
