NOTE:

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.

  • For the fabrication and repair of aluminum silicon alloys
  • Preheat at 100-300C is necessary depending on the base metal thickness and mass
  • Clean and free joint region from any contamination
  • The rapid electrode "burn of" rate ensures a fast travel speed
  • During welding, hold the electrode perpendicularly to the work piece and maintain a short arc length
  • Chill bars are recommended to provide support for the weld metal and avoid the possibility of "burn through"
  • Store the electrodes in a dry place
