Eutectic® 3055 Engineering Cast Iron Stick Welding Rod, 5/32"

Product # EUT3055-5/32
Price:
  • Regular price $34.50


  • Recommended for welding engineering-grade cast iron when you require mechanical properties similar to the base metal. Eutectic 3055 deposits a high-strength weld with excellent crack resistance properties on thick-section casting. Good for welding in all positions.

    Typical applications include pump and differential housings, motor blocks, high phosphorus irons and steels, heavy section casting repair, and dimensional restoration.

    Welding Parameters:

    Preparation: Thoroughly clean joints and parts to be welded. Stop crack growth by drilling 1/4" holes at leading points. Preheat casting to 150-200ºC, holding for 1 hour per inch of thickness. Prepare joints with Eutectic ChamferTrode® or ExoTrode® with either a single-V or a double-V, depending on joint thickness and accessibility. Allow a root opening of 1/8" for full penetration welds.

    Technique: Deposit short runs no longer than 2" and moderately peen 2nd any subsequent passes. For long cracks in heavy castings, use either a cascade and/or block deposition sequence.

    Post-Welding: Slow down cooling after welding using available material such as vermiculite, sand, or fire retardant blankets.
