NFG

Specification
AWS Specification: N/A
JIS Specification: N/A
Other Specification: N/A
Description
  • NFG is a special purpose chamfering rod that melts and removes metal along desired line of travel using an electric arc struck between the work piece and the electrode
  • Electrode coating is specially designed to concentrate a forceful and penetrating arc, stabilize the arc and prevent its extinction, and blow the motlen metal and dross away with a positive jet of gasses
  • Effective in cutting, piercing, and gouging metals and alloys that are difficult to machine (e.g. armor steel, air and deep hardening steels, stainless steels, cast iron, and work hardening overlays)
SIZE AND RECOMMENDED CURRENT RANGE: AC, DC (+)

Typical data and test results for mechanical properties, deposit, or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design, and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.

  • For the arc cutting, grooving and piercing of ferrous and non-ferrous metals, and back gouging of weld preparations for a wide range of repair and maintenance applications
  • Removing risers and gates from casting
  • Cutting heavy scrap prior to remelting
  • Cutting: With NFG metal sheet and plate up to 10mm thick can be metal-arc cut with ease, the electrode should be held at a shallow angle of about 15C to the surface of the plate With thicker plates an up-and-down motion should be made in the direction of thickness so that the molten metal and slag may run clear out of the cut
  • Grooving/gouging ? The force of the NFG arc removes the molten metal, by pushing it out in front of the groove, whilst a forward-and-backward motion. Where possible, the work piece should be inclined so that the molten metal can run free under the force of gravity
  • ? The speed of metal arc cutting is dependent upon the diameter of the electrode, current, and the plate thickness.
