This report presents the findings of an investigation aimed at determining those factors which control resistance to sulphide stress corrosion cracking (SSCC) in submerged arc welded (SAW) line-pipe. Two different SSCC tests were considered, these being the four-point bend test and the NACE tensile test. The materials studied were a series of laboratory welded plates, both accelerated cooled (AC) and thermomechanically controlled rolled (TMCR). Weld consumables of varying chemistry were employed to provide a wide range of weld metal microstructures. Factors studied in the present work included the weld metal P(cm), parent plate grain size, weld heat affected zone width, hydrogen permeation, weld metal microphase contents, and weld/plate diffusible hydrogen contents.
