Hobart Brothers has introduced a wire designed for welding high-strength steels that require good low-temperature impact toughness. The Hobart Fabco 107G all-position, gas-shielded, flux-cored wire offers a tensile strength in the 100-110ksi range in the as-welded or the post-weld heat-treated (PWHT) condition and is suitable for welding A515, A710, EQ56 and similar HSLA and QandT steels found in offshore and structural applications.According to the company, the wire can also be used to weld 4130 chrome-moly or 8630 nickel-chrome-moly pipes and provides excellent strength and toughness after PWHT (minimum 20ft/lbs at -20F). Hobart Brothers is offering the wire in two diameters: 0.045in (1.143mm) and 0.052in (1.321mm). The Fabco 107G wire has a smooth, stable arc that produces an excellent bead profile and helps to minimise downtime for the rework associated with quality issues.
The wire also produces low spatter levels and has a removable slag to help increase productivity and reduce post-weld clean-up. To minimise the risk of cracking, the Fabco 107G wire also features low diffusible hydrogen levels (3.7ml/100g with 100 per cent CO2 for the 0.045in wire and 4.3ml/100g with 100 per cent CO2 for the 0.052in wire). Hobart's Fabco 107G meets NACE MR0175 application requirements for both chemistry and hardness, as well as specifications for an AWS E101T1-GC H8 classification.
