New Hobart wire for high grade pipe

Published by
World Pipelines,

Hobart has introduced its new FabCO® 750M gas-shielded flux-cored wire.

The wire was designed to provide low diffusible hydrogen weld deposits (3.5 ml per 100 g of weldment) on high-strength applications and minimise 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 FabCO 750M 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 degrees Fahrenheit (-50 °C). It operates with a shielding gas mixture of 75 - 80% 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.
