Neutron diffraction residual stress measurements of welds made with pulsed tandem gas metal arc welding (PT-GMAW)

摘要

Pulsed tandem gas metal arc welding (PT-GMAW) is being developed to increase productivity and minimise weld-induced distortion in ship-building. The PT-GMAW process was used in pulse–pulse mode to butt-weld two different strength and thickness steels; the residual stress and hardness profiles of the welds are reported and correlated.
