Low Hydrogen Weld Deposit, Minimal Cracking Risks When Welding Pipe

Hobart Brothers Company (Troy, OH) offers their new FabCO® 750M gas-shielded flux-cored wire that is designed to provide low diffusible hydrogen weld deposits (3.5 ml per 100 g of weldment) on high-strength applications and minimize the risk of underbead cracking. It is especially well suited for welding API 5L Grade X100 pipe or as an overmatch on API 5L Grade X80 pipe. Other applications for this wire include high-strength, low-alloy steels; ABS EQ 56, 63 and 70 steel; and jackup rig construction. FabCO 750M wire features low spatter levels and an easy-to-remove slag to reduce interpass and post-weld cleanup, and lessen instances of inclusions. The wire also provides excellent arc characteristics, allowing operators to produce smooth weld beads with uniform fusion.

FabCO 750M wire offers high-impact strengths at temperatures as low as -60 deg F (-50 deg C). It operates with a shielding gas mixture of 75 percent to 80 percent argon and a balance of CO2, and provides a tensile strength of 121 ksi (using a 75/25 shielding gas mixture). The wire can be used for welding in all positions and is available in .045 in and 0.052 in diameters.
