The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. 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 50 kgf/mm2  high tensile strength atmospheric corrosion resisting steels and superior atmospheric corrosion resisting steels for bridges, structures, and rolling stock
  • Dry the electrodes at 300 - 350C for 30-60 minutes before use
  • Take the backstep method or strike the arc on a small steel plate to prevent blowholes at the arc starting
  • Keep the arc as short as possible
