Q&A: What to Know About FabCOR® Edge™ XP Metal-Cored Wire
What does FabCOR Edge XP provide to the industry?
This metal-cored welding wire delivers excellent weldability, meaning it has a balanced arc, low spatter levels and a smooth bead contour. Combined, these characteristics offer the industry a wire that can be relied on for consistent performance on a wide variety of joint widths and metal thicknesses. In tests, its overall appeal to welders is high.
What industries or applications can benefit the most from FabCOR Edge XP wire?
The wire is usable for truck, trailer and railcar fabrication, structural steel fabrication and the manufacturing of earthmoving, agricultural and forestry equipment. It can be used for semi-automatic, automatic and mechanized welding and for welding non-alloyed fine grain steels.
What skill level is the wire designed for?
FabCOR Edge XP wire is ideal for seasoned welders and new ones alike. The wire is easy to weld with and has appealing arc characteristics, so welders with a wide range of skill sets can create quality welds. For newer welders, the high weld pool fluidity and excellent arc control can help increase process forgiveness and simplify training.
What type of silicon control does FabCOR Edge XP wire provide?
The wire offers best-in-class silicon gathering on clean base materials. Its formulation ensures that the large silicon islands consistently migrate to the centerline of the weld for easy identification and removal. This reduces time for cleanup and helps prevent rework in paint applications.When welding over mill scale, the silicon control technology of FabCOR Edge XP wire can also provide some benefits.
What does this metal-cored welding wire offer in terms productivity?
FabCOR Edge XP wire offers fast travel speeds and high deposition rates, and it reduces the need for non-welding activities like spatter removal. This allows welders to spend more arc-on time creating quality welds for greater productivity.
What American Welding Society (AWS) classification and industry approvals does FabCOR Edge XP have?
The wire has an AWS A5.18: E70C-6M H4 classification and a CWB CSA W48: E491T15-(M12,M20,M21)A3-CS1-H4 classification. It has been tested in accordance with AWS D1.8/D1.8M: Structural Welding Code-Seismic Supplement.
How does FabCOR Edge XP wire compare to competitive wires with the same AWS classification?
Per competitive testing on clean base materials, FabCOR Edge XP wire excelled at silicon island formation, bead appearance and overall appeal compared to other wires. It also provided favorable bead appearance and overall appeal on materials with mill scale.
Can the wire be used for pulsed MIG welding?
FabCOR Edge wire is well-suited for use with pulsed MIG welding for out-of-position welding. For best results in all applications, Hobart suggests using a pulsed waveform program intended specifically for use with metal-cored wires. Most power sources allow fine-tuning of the arc length and width. Be aware that FabCOR Edge XP wire exhibits a relatively “crisp” arc having a slight crackle sound even at optimized parameters.
What is the optimal operating window for FabCOR Edge XP wire?
The optimal parameters in any application are primarily a function of the chosen wire diameter and desired deposition rate. FabCOR Edge XP wire is available in 0.045-, 0.052-, and 1/16-inch diameters, and is generally intended for use between 200 and 500 amps. Typical voltages range from 23 to 31 volts, though more voltage may be required when welding over mill scale or when using lower argon shielding gas mixtures. Hobart strongly advises consulting the FabCOR Edge XP wire data sheet when developing a welding procedure.
What deposition rates does the wire offer?
FabCOR Edge XP wire offers deposition rates ranging from 6.6 lbs/hr (3.0 kg/hr) to 24.7 lbs/hr (11.2 kg/hr) depending on the wire diameter and welding procedures used.
What kind of travel speeds can be expected with FabCOR Edge XP wire?
Hobart performed extensive testing to assess the travel speed capabilities of FabCOR Edge XP wire. Depending on the diameter and waveform used (pulsed or conventional MIG), it is possible to comfortably produce a 3/16-inch weld using travel speeds of 25 to 35 inches per minute. Fillet welds (1/4 and 5/16 inch) can be produced with speeds ranging from 18 to 22 inches per minute. Hobart suggests consulting its Application Engineering Department (800.532.2618) to better determine the maximum realistic travel speeds expected for a given welding application.
