Description

Application

Remarks

  • For higher carbon and alloy steels, apply a buffer layer of N-7016 to prevent cracking
  • Allow lateral weaving to attain broad, flat surfacing that is free of undercutting and spatter
  • Keep arc as short as possible
  • Preheat at 200ºC is recommended if carbon content exceeds 0.3%

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.
