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.

  • Ideal for buildups on parts subject to severe friction, compression, and moderate impact loads at elevated temperatures, such as shearing, blade, gripping pliers, gliding, and guiding surfaces
  • For production of cold and hot working tools
  • Preheat the workpiece to the recommended preheat temperature for the different type of tool steel
  • Hold electrode as vertically as possible and with a short arc
  • Allow the workpiece to cool slowly
  • Finishing by grinding
  • Re-dry electrodes that have got damp at 300° C for 2 hours
