“…Figure 4 right). This may be attributed to weld zones usually being more prone to corrosion than adjacent zones, generally considered caused by localised galvanic activity as a result of (usually small) compositional differences (Kato et al 1978;Brigham et al 1988) although microstructure and microbial activity also may be involved (Chaves and Melchers 2011). For this pipeline, a number of corrosion products were observed on the flush disc coupons, including iron sulphide (FeS), identified as pyrrhotite (Table 1).…”

“…E48018-1 < OK73 .08 < E55018-CI , there is a significant difference in the magnitude of the atta ck of both the weld metals and the baseplate s. F or example , in the earlier study [2), the baseplate was att acked to a maximum depth of approx . 0.2 mm and E48018-1 to a depth of approx.…”

“…The repair weld electrodes were chosen on the basis of chemistry as well as performance in a previous program [2]. These electrodes and their as-deposited weld metal chemical composition are listed in Table 2. E48018-1 was chosen as a typical electrode presently used in ship repair applications due to its improved toughness as compared to E48018.…”
