NICKELCAST

Specification
AWS Specification: N/A
JIS Specification: N/A
Other Specification: N/A
Description
  • NICKELCAST is a welding electrode that provides maximum strength for welding cast iron
  • Excellent crack resistance and porosity free
  • Soft arce prevents deep penetration
  • Weld deposit is easily machinable
  • No overheating of electrode
  • Special flux coating formulated to convert impurities of base metal into slag instead of being entrapped in the deposit
  • Little spattering and easy slag removal

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 fabrication and difficult repairs of all gray and alloyed cast irons
  • Recommended for welding cylinder heads, machine bases, gear housings, cams, levers, filling holes, reparing teeth of cast gears, and bulding up or replacing missing sections
  • Commonly used to weld ductile iron, "Ni-Resist" and "Meehanite" to themselves or to steel
  • Suitable for joining nickel alloys to gray cast iron, malleable cast iron, and cast steel
  • Prepare weld groove with NIHONWELD NFG Chamfering rod
  • Remove gouged surface skin by grinding U shape
  • Thoroughly clean weld area, removing all oil and grease as far or as deep as possible
  • Preheat is not necessary but for heavy and complex section, a preheat of 100-200 degrees C is advisable
  • Ensure electrodes are dry
  • Use lowest practical amperage and maintain a short arc technique
  • When restriking the arc, start on previously deposited weld metal, not on the base metal
  • Weld short stringer beads (about 20-30mm long) only to prevent excessive heat build up
  • When breaking the arc, always fill the crater and drag rod back over the weld deposit
