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.

  • Surfacing on machine components exposed to impact, compression, and abrasion at operating temperatures up to 550ºC
  • Suited for building-up dies
  • Rollers
  • Drive clover leaves
  • Hot shear blades
  • Preheat the workpiece to 250 ? 300ºC
  • Guide the elecrode as vertically as possible with medium-length arc
  • Let the workpiece cool slowly under asbestos
  • Finish by grinding
