Original Press Release
New Wire Offers Low Hydrogen (H4) Weld Deposits, Superior "as-Welded" and PWHT Properties
Press release date: March 28, 2012
TROY, Ohio. - Hobart Brothers has introduced a new welding wire to improve weld quality, particularly on offshore drilling rig applications and jack-up rig fabrication. The Hobart® FabCO® 712M gas-shielded flux-cored wire features less than 4 ml of diffusible hydrogen per 100 g of weldment, which decreases the chance of underbead cracking and can lessen the amount of preheating needed. The wire also has a very low moisture pickup, so there is less chance of hydrogen entering the weld after exposure to the atmosphere.
FabCO 712M wire features a fast-freezing, easily removable slag that makes it suitable for all-position welding and minimizes interpass and post-weld cleaning. The wire also offers low-temperature Charpy V-Notch (CVN) impact strengths (-40 to -75 degrees Fahrenheit [-40 to -60 degrees Celsius]), resulting in superior mechanical toughness properties in both the "as-welded" and post-weld heat-treat (PWHT) conditions. FabCO wire provides a tensile strength of 83 ksi in the as-welded condition and 80 ksi after PWHT.
Hobart Brothers recommends using a shielding gas mixture of 75 to 80 percent argon with a balance of CO2 with FabCO wire, and offers it in 0.045- and 0.052-inch diameters on 33-pound spools.
