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.

  • Welding of AISI309S and heat resisting cast steel
  • First layer welding of stainless clad steel 
  • Do no use excessive current in order to prevent the dilution from base metal in the case of welding of dissimilar metals and clad steel
