Validation of Assessment Methods for Production Scale Girth Welding of High Strength Pipelines with Multiple Pipe Sources

The goals of the proposed project are to: (1) test a large set of girth welds produced under realistic conditions by a state of the art high productivity gas metal arc welding (GMAW) system; (2) demonstrate the effect of material variability between pipes, between heats and between pipe manufacturers; and (3) validate current and proposed new weld defect assessment methods against the performance of a large set of welds made under field production conditions.
