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.

  • Structural joining, repair and surfacing of high manganese steel, tin bronzes (phosphor bronze) brass and copper
  • Commonly used  for ship propellers, turbines valves, thrust bearings, stirrer blades guides, suction rolls, parts of hydraulic equipment, construction machines, fitting, instrument, and pumps for the chemical paper industries
  • Preheat at 250 - 300ºC in the case of welding brass
  • Keep the arc length as short as possible
  • Do not use too much weaving
