High productivity welding of a modern higher niobium, low carbon pipe steel for high toughness applications

International Seminar on Welding of High Strength Pipeline Steels

2013
Starck, S
A new generation higher niobium X70 pipe steel has been welded using the high productivity submerged arc, multi-wire process with 2 passes for joining the longitudinal seams. High toughness weld deposits have been produced using a microalloying system produced using solid TiB SAW welding wires combined with a specially designed semi-basic SAW flux. High levels of toughness were produced in the weld metal and heat affected zone, evaluated using ISO-V and CTOD testing.
