New Metal-Cored Wire Minimizes Weld Cracking Risks
September 1, 2014
The Hobart FabCOR CVN metal-cored wire has been designed to provide excellent impact properties at low temperatures to reduce the risk of cracking in severe applications.
The Hobart FabCOR CVN metal-cored wire has been designed 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 3 ml per 100 g of weldment) further increase cracking resistance, reducing the cost and downtime of rework.
According to the company, the FabCOR CVN metal-covered 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 designed to maintain 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.
