Description

Application

Remarks

  • Dry the electrodes at 350-400C for about one hour before use
  • Store the electrodes at 100-150C after drying to keep away from moisture
  • Adopt back step method or strike the arc on a small steel plate to prevent blowholes at the arc starting
  • Keep the arc as short as possible
  • Pre-heat at 100-150C

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.
