NOTE:

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. 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.

  • Hardsurfacing of gears, shafts, and wheels
  • Preheating is unnecessary
  • But in the case of build-up welding of large cast steel and low alloy steel, need to preheat at 150-200ºC
  • The groove repairing is prone to slag inclusion so adjust the holding angle of the electrode
  • Dry the electrodes at 80-120ºC for 30-60 minutes before use
