TROY, Ohio. April 15, 2013 — The new Hobart® FabCOR® CVN metal-cored wire has been formulated to provide excellent impact properties at temperatures as low as -50 degrees Fahrenheit (-45 degrees Celsius) to reduce the risk of cracking in severe applications, including oil/gas piping and storage vessel welding; heavy equipment manufacturing; and structural fabrication. Low diffusible hydrogen levels (under 3ml per 100g of weldment) further increase cracking resistance, reducing the cost and downtime that rework makes necessary.

As with other Hobart-brand metal-cored wires, the FabCOR CVN wire offers high deposition rates and low spatter levels (compared to solid wires) to help improve productivity and improve weld quality. The wire’s smooth arc characteristics assist welding operators in the creation of a uniform weld bead, and the minimal slag coverage reduces cleanup time and minimizes the chance of inclusions. The FabCOR CVN wire is capable of maintaining good mechanical properties after stress relieving, making it suitable for use in critical applications that require post-weld heat treatment (PWHT).

Available in three wire diameters — .045, .052 and 1/16 inch — the FabCOR CVN wire operates with a 75 – 95 percent argon/CO2 balance and provides a tensile strength ranging from 77,000 to 86,000 psi (depending on shielding gas balance and “as-welded” versus PWHT conditions). It can be used for single- or multi-pass welding in manual, mechanized or automated applications.
