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.

  • Rebuilding of badly worn mild and alloy steel components
  • Repair of tractor idler wheels, rollers, and track links
  • Surfacing gears, mine rails, shovel pads, pins, and cluthes
  • Maintenance of shafts, wheel treads, and agricultural equipment
  • Preheat heavy sections or alloy steels in accordance with normal welding practice
  • Deposit is machinable
